current input is max. ±1% with respect to a reference
temperature of 25 °C.

Analog Output

The SHC Controller provides one voltage output ( terminals
33-35) able to produce a voltage signal (0...10 V).
Max. Current Draw
The max. current drawn from the voltage output is 1 mA.
Accuracy (10 kOhm load)
The accuracy of the voltage output (with a 10 kOhm load) is
max. ±25 mV.
Temperature Impact (10 kOhm load)
The temperature impact on the voltage output is max.
±100 mV with respect to a reference temperature of 25 °C.

Digital Inputs

The SHC Controller has three digital inputs (terminals 35-39),
capable of being configured to the following modes:
 the ENABLER digital input,
 the CLOSE digital input, and
 the REVERSE OPERATION digital input.
ENABLER Digital Input
If the ENABLER digital input (terminals 38/39) changes from
active to inactive, the SAFE procedure is performed. Then the
valve remains in the attained position until the ENABLER
digital input becomes active again.
If the ENABLER digital input changes from inactive to active,
the power-up procedure is performed, followed by the start-up
procedure.
NOTE: For description of SAFE procedure and START up
procedure refer to Operating Instructions which can
be downloaded from webpage
cooling.com
CLOSE Digital Input
If the CLOSE digital input (terminals 37/38) changes from
inactive to active, the valve is driven to CLOSED position and
remains so until the CLOSE digital input becomes inactive
again.
