Supply 12/24VDC to Controller as per drawing on page 7. Display will turn on and
indicate either Temp1 or Temp 2 which ever was selected by
½
push button. The
arrows up and down select the temperature set point. Once selected, the ignition
controller can be turned to the On position. This will initiate ignition controller, if
calling for heat and all shutdown inputs are clear. If the process is above the
temperature settings, it will not initiate lighting of the burner, but will turn on once
process drops below set point in the pilotless mode (I).
When the ignition switch is turned on and the controller is calling for heat, the
controller will attempt ignition and the pilot output will provide voltage to the
solenoid to allow pilot gas for ignition. Shutdowns, POC and remote on/off must be
in a permissive state for this to occur. Pilot output will cease if there is a failure to
light within 5 seconds and a FF will appear on the display. When using a single
trial module, the controller will lockout and have to be reset. When using a 3 try
module, the controller will attempt 2 more additional tries before locking out. This
can be reset either by the local on/off switch or the remote on/off switch. Whether
the I (pilotless or intermittent) selection or C (continuos pilot) selection is used, the
controller will perform as above except the continuous pilot will be initiated by on/off
as well as temperature demand switch, and remain on regardless of temperatures
setting.
The ACL CSC 200 Combustion Safety Control operates in a voltage range between
10-30 Volts DC. The terminals are #19 positive, #20 negative, and #22 ground.

The controller accepts two type K (ungrounded) thermocouples on terminals 1, 2, 3
and 4. They are clearly marked on the board for each thermocouple and polarity
(See wiring diagram). The temperature range can be selected via the dip switches
on the main circuit board located in the top right corner. Ranges can be selected
independently for each thermocouple input, either high or low. High range is -60 C
to 1100 C (-76 F to 2012 F) or low range, 0 C to 500 C (-32 F to 932 F).
The switch on the side of the controller is internally wired to terminals 5 and 6.
This turns on and off the ignition module provided the shut down input and remote
reset inputs are closed and temperature values for both thermocouples are in a
permissive range. The On/Off switch also acts as a reset to clear any latched shut
downs that may have tripped then cleared.
