The ACL 5100 combustion safety controller is designed to ignite and prove a
continuous pilot while monitoring and annunciating multiple heater shutdowns for
all types of gas fired heaters and industrial sized burner applications.
The ACL 5100 utilizes a single ignitor/flame rod to provide both flame
acknowledgment and ignition at the pilot tip. When the ACL 5100 starts its
ignition sequence, fuel gas travels to the pilot tip where the ignitor/flame rod is
located and sparking. Once the gas is lit, the flame becomes a current path for
flame acknowledgment and the unit stops sparking. After the pilot has been
proven for 20 seconds (factory set) the ACL 5100 will allow gas to the main
burner.
If the pilot flame is extinguished, the current path is broken and the ignitor/flame
rod starts sparking within 1 second to attempt to re-light the pilot. The main is
shut off during this re-light period. If a flame is not established within the 5
second sparking period, the controller will immediately drop the output to
solenoid #1 pilot gas valve. The controller will attempt to light 2 more times with
15 seconds between each trial when equipped with three trial ignition module. If
the flame is still not lit, the flame fail alarm will be indicated by a continuous
alarm light.
If any of the shutdowns are tripped, the controller will not attempt any re-light,
and solenoid outputs will de-energize immediately. A shutdown will then be
indicated by the flashing alarm light. The shutdown must be cleared before the
controller will allow an ignition cycle.
The controller also has a power fail indicator to determine brownouts or power
disconnection and this is indicated by a flashing system on light after power has
been restored.

OUTPUTS
The ACL 5100 can be mounted in a Class I, Div 2 area; usually close to the
burner. The 10’ of high voltage lead, (longer lengths are not recommended) must
be run in the non- metallic flex (provided) or free air. If the high voltage lead is
run in the non-metallic flex, a conduit seal (provided) must be installed. Note:
Lead lengths in excess of 10’ or use of metal or metallic sheathed conduit may
result in a diminished ignitor rod voltage. A ground wire (also supplied) must be
connected between the ground lug on the burner assembly and the bonding
ground terminal on the main circuit board. Note: If the controller must be
mounted farther away from the burner assembly, the ignition module, which is
mounted on the main circuit board, may be mounted in or near the burner
housing using the optional, CSA approved, ACL 5000R remote mount kit. Do not
coil excess high voltage lead inside controller enclosure. High voltage magnetic
field may damage sensitive components. Electronic components and cables in
close proximity to the ignition module and ignition cable may be affected by high
voltage noise.
The ACL 5100 is available in 12/24 VDC and 120/240 VAC. Voltage
requirements must be specified when ordering. The supply voltage of each unit is
clearly marked inside the door on the specification label and on the circuit board
beside its respective terminal. Incorrect polarity on 12/24 VDC units may result in
damage to circuit board components. The terminal marked ground is for supply
or system ground and the terminal marked bonding ground is strictly for the
ground wire to the burner assembly. It is important that a ground wire (supplied)
be connected between the bonding ground terminal and the burner assembly to
provide an uninterrupted path for the flame acknowledgment current.
There are two solenoid output terminals on the main circuit board marked pilot
solenoid and main solenoid. The output voltage at these terminals is always the
same as the controller supply voltage. The pilot solenoid output connects to the
pilot or low fire solenoid and is energized when a start is initiated. Main solenoid,
(main burner) energizes only after the pilot or low fire flame has been proven.
The time delay between proof of flame and energizing of main output is factory
set at 20 seconds. Available in all three voltages).

S/D INPUTS The shutdown input provides a means of connecting other shutdown devices
such as low level, high temperature, low gas and high gas shutdowns for
additional protection. A jumper is installed at the factory and should only be
removed to utilize this feature. Shutdown devices connected (in series) to the
shutdown terminal, and be in a closed state during normal must be dry contacts
operating conditions. If any of the S/D switches go to fault condition, their
contacts will open, de-energizing the solenoid outputs and shutting down fuel to
the pilot and main burners and disabling the re-light sequence. This will be
indicated by the alarm light flashing. Once the fault condition is corrected the
system can be restarted by pressing the stop/reset and then the start buttons.
Note: if a restart is attempted without clearing the fault condition, the controller
will not attempt a re-light. Do not run shutdown loop wire in the same conduit as
solenoid wiring. Induced voltage may damage sensitive circuit board
components.
The remote S/D function is available when the jumper is removed and a
momentary normally closed contact button or remote relay contact (N/C) is
utilized. Note: Must be dry contacts.
The remote start function is available when a momentary normally open contact
button or remote relay contact (N/O) is utilized. When contacts close
momentarily the unit initiates starting sequence. Note: Must be dry contacts.
This feature allows controller to use valves with proof of closure switches for
ensuring main valve is closed before initiating an ignition. When valve switch
contacts are in an open state indicating the valve may be open, the controller will
not start. The contacts must be closed in order for controller to start. Once start
is initiated, the contacts from proof of closure switch can then change state.
The system on light indicates power supplied to the ACL 5100. When it is
flashing it indicates there has been a power failure.
A solid light indicates the pilot has failed to ignite. A flashing light indicates a
shutdown is open.
Alarm status is provided from a set of normally open/normally closed dry
contacts which change state when a pilot flame is detected. If the pilot goes out
due to any of the shutdowns or fails to re-light, the contacts return to normal or
alarm state.
