1. Input power for the controller must be 240VAC,
single phase, 60 Hz or 220VAC, single phase, 50 Hz.
2. Controller terminals
a. 18 to 12 AWG wire size for heaters and controller.
Use appropriate thermocouple wire for thermocouple
and application.
b. Torque to 7.0 lb-in (0.8 Nm)
c. Wire strip length 0.30 in (7.6 mm).
3. Relay input terminals for use with N size pump only
(terminals 7-16)
a. 24 to 16 AWG wire size
b. Torque to 4.4 lb-in (0.5 Nm)
c. Wire strip length of 0.22 in (5.5 mm)
4. Relay line and load terminals for use with N size pump
only (terminals 1-6)
a. Will accept 18 to 8 AWG wire size
b. Torque to 12 lb-in (1.4 Nm)
c. Wire strip length 0.25 in (6.35 mm)
d. Retorque after 48 hours to minimize wire cold flow
e. Retorque terminals every 3 to 6 months
f. Ground terminal use spade terminal for No. 8 screw,
with upturned lugs
g. Attach grounding wire to grounding screw (#6)
5. Maintain electrical isolation between thermocouple analog
input 1 (terminals S1 and R1), any digital inputs-outputs,
and process outputs 1 and 2 (terminals L1, K1 and L2,
K2, respectively) to prevent ground loops.
6. To prevent injury and damage to the controller, do not
connect wires to unused terminals.
7. The wires for the heat cartridges can be joined together in
a junction box, and a single wire from the junction box can
be connected to the controller.
8. The wiring diagram is only valid for standard type J
thermocouples and controllers supplied from Viking Pump.
9. For information on the location and installation of the heat
cartridges and thermocouple, please see the TSM for
your specific pump. The thermocouple will require a fitting
adapter which is included with the controller kit in order to
mount to the pump.
