2 1.0 Introduction Overview This instruction covers the replacement of an existing control output printed circuit board (Subsection 2.0) and the addition of one of the following control output printed circuit boards: 4 to 20 ma Output (Subsection 3.0) Position Proptional Output (Subsection 4.0) Relay Output (Subsection 5.0) Common causes of failure Two of the most common causes of failure of this card are: Excessive load on the output board relays Supply Voltage (Example 115 Vac) Resistance of Customer Controlled Device = Must equal a number less than 5 (Amps) Noise damage to the slidewire circuit (Position Proptional Output) See Application Notes in this instruction - Subsection 6.0. Limitations Only one control output is available on any of the DR4500A recders except on the DR45AT and DR45AP recder which can have two control outputs. The DR45AH HTST and DR45AS STLR recders come standard with one control output since this is necessary f this application; therefe, this unit cannot be upgraded to add any control outputs. The Setpoint Programming feature has been made a standard part of the control output option on the DR45AT and DR45AR recders and no longer is specified separately as was the case with the DR450T DR450R Recders. The DR4500A recder cannot be upgraded with the FM approved control output in the field since additional facty tests are required to attach the FM logo. If you are adding a Control Output and the recder does not have Communications option a Third Fourth Input, you will need to der a Motherboard, Part Number WARNING Never access components inside the case with the power applied. CAUTION When handling electronic assemblies, care should be taken to avoid damage by electrostatic discharge. Use a wrist strap connected to an earth ground befe removing the suspect board withdrawing the replacement from its container and installing it into the recder. 2 of 20 Replacement Kit Instruction # C 9/96

11 4.1 Position Proptional Output Calibration Position proptional control When the DR4500A Recder has a position proptional control output, calibrate the recder so that the open and close relays operate properly with respect to the position of the external feedback slidewire. Equipment needed None Connections Leave all field wiring connected to the plugs in connects J2 and J5 on the appropriate control output printed circuit board. Apply power and allow the recder to warm up 15 minutes befe you calibrate. Auto mode vs manual mode There are two ways in which to calibrate Position Proptional control: AUTO mode MANUAL mode. Rules f auto mode vs manual mode The auto-mode selection must be done at least once befe the manual mode will operate properly. Failure to use the auto-mode procedure will prevent the recder from going into automatic control mode. Displayed values During the auto-mode calibration procedure, the values being displayed are used only to indicate if the mot is still traveling. To view the actual calibration value, use the manual mode after the automode is completed. These values can be changed f purposes of fine tuning the calibration.
