6 Description Mercury Pulse Accumulator The Mercury Instruments Pulse Accumulator is a 2-channel, battery-powered electronic recorder that is designed to receive and store low-frequency pulses. Two independent pulse sources may be connected to the input channels, each having its own 3.5vdc wetting voltage. Since the two channels act as independent accumulators, typical installations might include: a) One pulse source (pulse transmitter or meter pulse) connected to either Ch1 or Ch2. b) Two separate pulse sources (pulse transmitters or meter pulses) connected to Ch1 for the first source and Ch2 for the second source. c) Pulse outputs from one volume corrector connected to both channels, Ch1 for corrected volume pulses and Ch2 for uncorrected volume pulses. In an operational Pulse Accumulator, pulses received at either input are assigned a fixed amount of volume via their respective Input Pulse Value selections. Additional pulse scaling can be applied using their respective Input Pulse Scaling items (if needed) before the pulses are stored (added) to their respective accumulated totals. Ch1 versus Ch2 volumes units can be independently scaled. The number of digits (from 4 to 8 digits) can also be assigned for both channels. Below are the items associated with Accumulated Volumes: Ch1 Item# Ch2 Item# Input Pulse Value Input Pulse Scaling (this feature is normally not needed) Accumulated Volume Incremental Accumulated Volume Accumulated Volume Units Accumulated Volume # of Digits

7 Mercury Pulse Accumulator Additionally, each pulse channel may also be configured to receive a user-specified FixedFactor multiplier. By default, this multiplier is disabled but may be activated by inserting the desired factor into item 044 for Ch1 and item 440 for Ch2. The FixedFactor feature is normally used to adjust the accumulated uncorrected volume for a fixed pressure factor or fixed temperature factor (or both). Below are the items associated with FixedFactor Volume: Ch1 Item# Ch2 Item# FixedFactor Volume Incremental FixedFactor Volume FixedFactor Value FixedFactor Volume Units FixedFactor Volume Digits The basic Pulse Accumulator assembly includes a Mercury Instruments Messenger Modem to provide telecommunications. The Pulse Accumulator can receive host-initiated calls (Call-out) or provide instrument-initiated calls (Call-in). Call-in type calls can be the result of an instrument Alarm, a Scheduled call or the shorting of the Force-a-call jumper pins. The Force-a-call pins are located at J1 on the Pulse Accumulator circuit board. (If specified, an optional externally-mounted push-button may be installed and connected to the pins at J1. That way, a call can be forced without removing the cover from the enclosure.) The Force-a-call function can only be used if item 333 (Call-In Trigger) is set to Alarm Call-in, Scheduled Call-in or both. If instrument-initiated calls fail to connect to a host system, primary and secondary call-in retries are activated in an effort to complete the call-in process. When some other communication device (such as cellphone, radio, etc.) is substituted for the Messenger Modem, the Pulse Accumulator s Power Control feature can periodically apply power to that modem device. This feature is useful when the communication device is battery powered and extended battery life is needed. The majority of the items from 485 to 497 are used to configure the power-on start time, stop time and interval length as well as the number call retry attempts and spacing. 7

13 Item Code Types There are two basic types of item codes used in the Pulse Accumulator, Direct-read and Configuration. The Direct-read items are mainly used to store information or to accumulate readings. Except during the initial installation, these types of items are normally just read periodically to obtain the accumulated information. However, if needed, these values may be changed by directly typing in new information from the keyboard. Configuration items are used to configure or customize the Pulse Accumulator to provide specific functions or features. Usually, these items require choosing an option from a list. When using MasterLink (version 3.50 or higher), the available options are presented as text messages. However, if using an older version, the Raw Item Access feature must be used to send a numeric codes to the items that need changed. To gain Raw Item Access Link to the Pulse Accumulator, then click: Setup\Advanced\Raw Instrument Access\Raw Item Access. 13

14 Mercury Pulse Accumulator From the Raw Item Access window, enter the 3-digit item number and click Read. The Item Value field will display the current code for that item if the status returns the message Item Read Successful with a green background If a different value for that particular item is needed, change the value in the Item Value field and click Write. You can immediately click the Read button again to confirm the intended value was actually stored in the instrument. Since the numeric codes for the Configuration items may not be readily apparent, use the item list on the following pages to determine the required codes. 14

18 Installation Mercury Pulse Accumulator The Pulse Accumulator is designed to be a wall-mounted, battery-powered electronic recorder of low-frequency pulses or switch closures. The internal 2400 baud modem is to be connected to a standard phone line to communicate accumulated reading to a host computer system. Use the wiring diagrams on the following pages when making connections to the unit. Use the following steps as a general guide when installing the unit. 1) While viewing the front of the Pulse Accumulator assembly, rotate the case until the two case fittings are in the downward position. 2) Using the four mounting tabs (attached) and four screws (not included), attach the enclosure to a flat surface, usually a 1/2 thick piece of plywood. 3) Loosen the four screws in the corners of the lid. Remove the lid and set aside. 4) Install the battery pack into the battery compartment. Make sure the aluminum plate attached to the battery pack is positioned to the right before inserting. Plug the battery cable into Pulse Accumulator board at J4. 5) Route the wires (cable) from the remote switches or pulse output device through the right-side case fitting. Continue routing the wires through the right-side and top wire looms. Connect the input switch wires to Pulse Accumulator board at TB2. 6) Route the phone wires (cable) through the left-side case fitting and left-side wire loom. Plug the phone cable into the modem board at J2. 7) Unplug the CMOS ribbon cable from the Pulse Accumulator serial port J5. Connect an MPA ribbon cable into J5 and the other end to a standard I/O serial cable. Plug the DB-9 connector of the I/O cable into the computer serial port. 8) Run MasterLink32 software and link the instrument. Use the Set Instr. Date/Time via Computer selection in the Instrument menu to set the date and time in the instrument. 9) Use MasterLink32 to set the Input Pulse Value for Ch1 at item 098 and item 912 for Ch

19 Mercury Pulse Accumulator 10) If the Input Pulse Value is not listed at items 098 and 912, use Input Pulse Scaling at items 114 and 913 to further define the pulse values. Example: If a switch closure from the meter is to represent 2 CF, set item 098 (912) to 1 CF and then set item 114 (913) to a value of NOTE: Leave items 114 and 913 to if the proper pulse value can be selected at items 098 and ) Set item 092 for the desired Accumulated Volume unit-of-measure, i.e. CFx10, CCF, MCF, m3, etc. This setting will be applied to both Ch1 and Ch2 Accumulated Volumes. 12) Set the accumulated reading at items 002 and 910 to zero, or some other known starting value. 13) The Mercury Pulse Accumulator has the ability to apply FixedFactor correction to the Accumulated Volumes. If FixedFactor is needed for either of both channels, change the values at items 044 (Ch1) and 440 (Ch2) from to some greater value. Typically, FixedFactor correction will be used to apply a pressure correction factor, or temperature correction factor or both. When FixedFactor correction is applied, items 000, or 908 or both will advance from its default value of zero. 14) Set item 090 for the desired FixedFactor Volume unit-of-measure, i.e. CFx10, CCF, MCF, m3, etc. This setting will be applied to both Ch1 and Ch2 FixedFactor Volumes. 15) Use item 097 to set the desired number of digits displayed for Accumulated Volume. Use item 096 set to the desired number of digits displayed for FixedFactor Volume. 16) Set items 200 and 201 to the Site ID numbers assigned to this particular unit. Do not duplicate Site ID numbers for other units. 19

20 Mercury Pulse Accumulator 17) In its default configuration, the Pulse Accumulator should be able to receive calls via its internal modem. If the Pulse Accumulator is to also call into a host system, set item 486 to Yes. Also set the following items to their most correct or most appropriate settings: 333 Call-In Trigger 334 Sched Call-In Date 335 Sched Call-In Time 336 Call-In Retry By: 338 Sched Call-In Occurred 339 Sched Call-In Phone Num 493 Alarm Call-In Phone Num 18) If the Pulse Accumulator is set for Call-in (item 486 = Yes ), then set the following items for their most appropriate settings: 495 Modem Retry Interval A 5 (Default) 496 Modem Retry Interval B 1440 (Default) 497 Modem Retry A Count 3 (Default) 19) If the Pulse Accumulator is connected to an external modem and the Power Control feature is to be used to periodically apply power to the modem then set the following items for their most appropriate settings: 490 Call-out Start Time (Default) 485 Call-out Stop Time 23:59:00 (Default) 489 Call-out KeepAlive Time 0 (Default) 488 Call-out RepeatInterval 0 (Default) 487 Call-in Keep Alive Time 15 (Default) 20) When all items are set to their desired values, disconnect link and unplug the MPA cable from J5. Reinsert the modem ribbon cable into J5. 21) Reinstall the cover (lid). The lid is not a perfect square so be sure it s rotated to the correct orientation. NOTE: Tighten the four cover screws to in. lbs. using a 1/4" flatblade screwdriver. Also, overtightening the screws may damage the assembly and the use of a smaller screwdriver may damage the screws. 20

21 Power Control Mercury Pulse Accumulator Although not always needed, the Power Control feature (via A- & A+ at TB1) is used in conjunction with items to apply power to a battery-operated external modem. The purpose of the Power Control feature to provide a time-schedule for limiting modem operation (usually 10 to 60 minutes per day) as a means of extending modem battery life. If a wireless battery-powered modem were to remain powered continuously, the batteries may only last several days to several weeks. With Power Control, it s possible to extend battery life for months. In some situations, battery life greater than a year can be obtained. The trade-off is that the modem will only be available at certain time(s) during the day and only for the specified number of minutes. When the Power Control feature is enabled, any call-in (Alarm or Scheduled)) will also activate power for the modem and remain powered for the time interval specified at item 487 (Call-in Keep Alive Time). The default setting of 15-minutes should be adequate time to call back out to the unit to retrieve additional information following a call-in. 21

22 Mercury Pulse Accumulator Pulse Accumulator Wiring The drawing below will appear as a label on the inside of the Pulse Accumulator lid. This diagram indicates the recommended placement of field wires (or cables) brought into the Pulse Accumulator enclosure. Per the diagram, pulser wires from the meter switches (or pulser output) are to be routed through the right-side case fitting and then through the three gray wire looms mounted on the white battery plate. The wires are to continue through the single wire loom along the top before being routed down to TB2 on the Pulse Accumulator board. The telephone cable is to be routed through the left-side case fitting and then through the single wire loom along the left-side of the enclosure. Plug the phone cord into J2 of the Messenger Modem. NOTE: To avoid potential damage from transient surges, when installing telephone and pulse input wires, keep the wires as short as possible and do not rest any access wires on either circuit board. 22

23 Mercury Pulse Accumulator Simplified Wiring Diagrams (with internal modem) The following diagrams can be used to assist in the wiring of Pulse Accumulators during installation. Either or both pulse channels may be wired to a remote Form-A (2-wire) switch or pulse output device. A 3.5 volts DC wetting voltage is provided by each Pulse Accumulator input channel. Be sure to observe polarity if the pulse channel is to be wired at an active device, i.e. transistor-type output. Note, for reasons of clarity, the case fittings are not shown in their proper relative positions. See the diagram on the previous page for a more true representation.
