SYSTEM CHECK

Before you energize the controller, confirm:

∙All the sensors, relay coils and the power supply are connected to the proper terminal blocks.

∙Only approved cable was used to extend the sensors.

∙The polarity of the 120 VAC power supply is appropriate.

∙You have connected the output terminals to a relay or contactor coil, NOT DIRECTLY TO THE HEATER LOAD.

After energizing the controller, you should see:

∙The display lit and reading the temperature in the area of the SMTS-1.

∙The Small green LED’s next to the connected terminal blocks are lit (no LED for the SMTS-1 block).

To cycle system and check sensor operation:

1.Submerge the SMTS-1 in a quart (litre) of water and crushed ice.

2.After 20 minutes, confirm the display reads 32°F (0°C).

3.Put a drop of water on each sensor surface*, the Power Relay light(s) on the front panel will light up and the associated output relay will energize.

4.Dry off the sensor surface; the relay output will de-energize and the relay light will turn off after the pre-set hold time.

*To confirm SMPS-1 operation, the slab temperature must be below 59°F (15°C).
