3-3 High Pressure Cutout

The high pressure cutout is an electro-mechanical safety feature that opens the control circuit if the system condensing pressure exceeds a safe level. The chiller will automatically restart when the pressure drops back to an acceptable level.

Model

Cuts out if condensing pressure exceeds:

SMC050

275 psi (1,897 kPa)

SMC100

275 psi (1,897 kPa)

SMC150

400 psi (2,759 kPa)

IMPORTANT!

Call a refrigeration service technician to analyze

the problem if high pressure recurs.

3-4 Low Pressure Cutout

The low pressure cutout is an electro-mechanical safety feature that prevents compressor suction pressure from dropping below a preset point.

It is factory set to open the control circuit when pressure drops below a safe level. The chiller will automatically restart when the suction pressure reaches an acceptable level.

Model

Cuts out if suction pressure falls below:

SMC050

15 psi (103 kPa)

SMC100

15 psi (103 kPa)

SMC150

35 psi (241 kPa)

3-5 Remote Start/Stop Interlock

A contact is provided to allow interlocking of the SMC Series Chiller with process controls. To use this feature, remove the jumper between Terminals X1 and 1 on Terminal Block 1. Supply a switch or dry contact interlock connected in series between these two terminals. See Figure 15 and Figure 16 on pages 34 and 35 for more information.
