1 T775S Series 000 Expansion Module INSTALLATION INSTRUTIONS PRODUT DESRIPTION The T775S008 Relay Expansion Module is a four relay device for use with the T775L007 and T775P00 Series 000 Electronic Stand-Alone ontrollers. The T775L and T775P controllers each comes with four relays and can accept up to two T775S Expansion Modules, which can provide a total of up to relays for each controller. The T775P and T775L controllers are the next generation of commercial and agricultural controls capable of remote sensing of temperature and providing switched and/or proportional outputs to various types of loads. When used with the T775L007 model, the T775S Expansion Modules provide the capability to have up to two PID control loops, which can be used to stage multiple relays (up to when using two T775S modules) from two independent heat or cool setpoints. The number of stages for each setpoint can be freely chosen, limited only by the number of relays available. When used with the T775P00 model, up to stages (when using two T775S modules) with reset may be configured with the last stage being an option for a pump stage. IMPORTANT The T775S expansion module is an operating control, not a limit or safety control. If used in applications requiring safety or limit controls, a separate safety or limit control device is required. Table.

INSTALLATION AND SETUP The following installation procedures are typically performed in the order listed:. Mounting see Mounting below.. Wiring see Wiring on page 4.. heckout see heckout on page 8. TE: Troubleshooting begins on page 8. MOUNTING IMPORTANT Avoid mounting in areas where acid fumes or other deteriorating vapors can attack the metal parts of the controller circuit board, or in areas where escaping gas or other explosive vapors are present. IMPORTANT The controller must be mounted in a position that allows clearance for wiring, servicing, and removal. Use a screwdriver to pry out only the knockouts that you will use. If mounting on DIN rail, be sure to remove the knockouts before mounting. See Wiring Access and Fig. 4 on page 5 for recommended knockout usage and locations. If you do not use an opened knockout be sure to cover it. Mount the controller on any convenient interior location using the four mounting holes provided on the back of the enclosure using #6 or #8 screws (screws are not provided and must be obtained separately). Use controller dimensions in Fig. on page as a guide. The controller may be mounted in any orientation. WIRING WARNING Electrical Shock Hazard. an cause severe injury, death or property damage. Disconnect power supply before beginning wiring, or making wiring connections, to prevent electrical shock or equipment damage

4 AUTION Do not use 4 Vac power to power any external loads if 0 Vac or 40 Vac is used to power the T775S controller. AUTION A separate earth ground is required. Equipment damage can result if the earth ground is not connected. See Fig. and Table on page 5. AUTION Equipment Damage Hazard. Electrostatic discharge can short equipment circuitry. Ensure that you are properly grounded before handling the unit. W Knockouts, D, and E can be used to gain access to the load relay output terminals and 0/40 Vac power wiring. See Fig. 4 on page 5 for locating the appropriate power input, T775 Bus connection, and load output terminals. Wiring Method Wire the outputs, the bus connection, then wire the power connection. Each terminal can accommodate the following gauges of wire: Single wire from 4 AWG to AWG solid or stranded Multiple wires up to two AWG stranded For 4, 0, or 40 Vac power connections: Single wire from 4 to 8 AWG solid or stranded Prepare wiring for the terminal blocks, as follows:. Strip / in. ( mm) insulation from the conductor.. ut a single wire to /6 in. (5 mm). Insert the wire in the required terminal location and tighten the screw.. If two or more wires are being inserted into one terminal location, twist the wires together a minimum of three turns before inserting them to ensure proper electrical contact. 4. ut the twisted end of the wires to /6 in. (5 mm) before inserting them into the terminal and tightening the screw. 5. Pull on each wire in all terminals to check for good mechanical connection.. STRIP / IN.

TE: A jumper is required on the second T775S. This jumper identifies the relays (9, 0,, and ) on the second T775S to the controlling device, the T775L or T775P. Each controller may be powered by 4 Vac, 0 Vac, or 40 Vac. A separate earth ground must be connected to the 4 VA ground terminal, regardless of the power source. The T775P or T775L is able to use up to four relays ( through 4). However, it may be configured to use any or all of its relays. Each T775S Expansion Module is able to use up to four relays (58 or 9). However, it may be configured to use any or all of its relays. HEKOUT Inspect all wiring connections at the controller terminals, and verify compliance with the installation wiring diagrams. WARNING Electrical Shock Hazard. an cause severe injury, death or property damage. Disconnect power supply before beginning wiring or making wiring connections, to prevent electrical shock or equipment damage. If any wiring changes are required, first be sure to remove power from the controller before starting work. Pay particular attention to verifying the power connection (4, 0, or 40 Vac). After the expansion module is installed and wired to all loads and interconnects, apply power. Programming and Setup Use the appropriate Installation Instructions document for the controlling device (T775L or T775P) to set up and program the system: T775L007 - T775L Series 000 Electronic Stand-Alone ontroller (form 6-057) T775P00 - T775P Series 000 Electronic Stand-Alone ontroller (form 6-056) TROUBLESHOOTING The controlling device, the T775L or T775P controller, provides an error message and diagnostic status as described below. Error Message There is a two-character error code that displays on the T775L or T775P controller in response to controller software problems: EE EEPROM Failure The values read back from the EEPROM are not the same as written into the EEPROM. This error cannot be field repaired. Replace the device. Diagnostic Messages There are two diagnostic messages that can display on the T775L/T775P controller in response to sensor problems. The diagnostic codes that can flash on the display are: Sensor Open or Shorted Two dashes display when a sensor (typically temperature) is open or shorted. An open circuit is considered anything greater than 570 ohms (greater than 00F), shorted is anything less than 770 ohms (less than -7F). Whichever stages are operating with this sensor cease to control (meaning relays go to OFF and proportional outputs go to zero percent). This message can also mean that the sensor is programmed, but not physically connected. -60 F or 70 F (-5 or ) Blinking Temperature Out of Range The temperature display blinks when the sensed temperature range is outside of the display range, below -60 F (-5 ) or above 70 F ( ). The displayed value remains at that displayed limit and control continues. ontroller continues to function unless an open or shorted state is detected. Blinking relay status Relay Minimum Off Time is Active On the T775L or T775P home screen, each relay s indicator ( ) blinks while the relay s minimum off time is active.
