The following inputs directly control 12VDC power output to the ignition modules and must be connected to dry contacts:
Input and Control Connections
Requiring Dry Contacts Voltage on Control Inputs Output and Control Connections
That Are Dry Contacts
Proof Of Closure 12VDC
Remote Start/Stop 12VDC
High Gas (Pres) Shutdown 12VDC
Low Gas (Pres) Shutdown 12VDC
Level Shutdown 12VDC
Auxiliary Shutdown 1 12VDC
Auxiliary Shutdown 2 12VDC
N/A AUX1 Relay
N/A AUX2 Relay
Alarm Status N/A Alarm Status
Interruption or disconnection of the Remote Start/Stop or Shutdown inputs will turn off or prevent power delivered to the ACL
ignition module and turn off power to all solenoids with the exception of the Proof of Closure input. The Proof of Closure
input will only interrupt power going to the ignition module if power has not been turned on already to the ignition module. If
the system is already running, the Proof of Closure input is allowed to open during operation.

Main Power Input
The ACL CSC400 Combustion Safety Controller operates on an input voltage range between 10 and 30 Volts DC. Typical
input voltages are 12VDC and 24VDC. Whatever input voltage is delivered to the CSC400 on the Main Power Input terminals
is the same voltage delivered to the solenoid outputs. Solenoids attached to the three solenoid outputs on the CSC400 (Pilot,
Main, T/Main) need to have matching control voltages (Eg. all 12VDC or all 24VDC).
Although the CSC400 will operate with input voltages as low as 10VDC, some larger solenoid valves may not operate on such
a low voltage. For this reason, try to maintain the input voltage as close to (or slightly higher than) the required voltage for the
desired solenoids.
The Main Power Input terminals are:
Terminal Number Description Typical Input Values Allowable Input Range
35 VDCIN + (positive) 12VDC or 24VDC 10 VDC (min) - 30 VDC
(max)
36 VDCIN - (negative) 0V (GND) 0V (GND)
