1.2 Wiring for Operaon
This secon covers general wiring for most common
applicaons. Important! All wiring should be done
in accordance with local regulaons and within the
specicaons of the site or equipment owner. If there
are quesons not answered by this manual or the wiring
diagrams, please call Cimarron Energy at 1-844-746-1676
for assistance.
1.2.1 Connecng the Power
The ARControl is designed to operate from either 12 or 24
volt power supplies or baeries. Power supplies should
be rated Class II and capable of sourcing a minimum of 2
amps. Baeries should be either 12 or 24 volt and have a
minimum 12 Ah (amp-hour) capacity.
1.2.2 Connecng a Solar Panel and Baery
(if required)
Solar Charing
The ARControl contains an integrated solar charger. The
solar charger is capable of charging a 12 volt 12 Ah SLA
(sealed lead acid) baery. A solar panel rated for 12 volt
systems with a maximum current output of 2 amps is
recommended. Installaons that require more charging
current than provided by the internal solar charger should
ulize a properly sized external solar charger and baery
(Image 1.2.1).
Power Pack
The standard ARControl Power Pack (PN: 1960-160)
contains a 12 volt 12 Ah SLA baery in a sturdy DIN-
mountable bracket and a 5 wa 12 volt solar panel with
9 feet of cable and a mounng bracket. The baery and
bracket clips onto the boom DIN rail in the ARControl
enclosure. The solar panel can be mounted with a U-bolt
to a pole or to any other structure that
can accommodate the mounng holes. Be sure to
locate the solar panel south facing in an area free from
obstrucon of the sun throughout the enrety of the day
(Image 1.2.2).
Fusing
The ARControl has three user-replaceable fuses. The fuse
on the DIN rail mounted terminal block that connects to
BATTERY IN on the ARControl ulizes a 5 amp ATC or ATO
fuse. The ARControl board is fused at both the POWER
PORT and MODULE PORT with 2 amp ceramic fuses (PN:
3181-002). The POWER PORT fuse protects all of the valve
outputs and the digital outputs. The MODULE PORT fuse
protects the power output to the Ignion Module. There
are two spare 2 amp ceramic fuses located in the SPARE
FUSES locaon on the ARControl board.

1.2.3 PERMISSIVE (DIN) Input
The PERMISSIVE input is used to
shutdown the system if it is acve.
Connect the input to a PLC or some
other external switch. By default,
the input is acve when the circuit is
open but this can be changed in the
IO sengs. It is internally pulled up to
5 VDC. If it is not used it needs to be
jumpered (Image 1.2.3).
1.2.4 Proof of Closure Input
The PROOF OF CLOSURE input is used
to check that a valve is closed before
the system aempts to ignite.
Important! Failure of this test will
transion the system to the POC
FAILURE state.
Connect the input to a valve’s status
output, pressure switch, or other
device intended to prove the state of
the valve. By default, it is acve when
the circuit is open but this can be
changed in the IO sengs. The input
is internally pulled up to 5 VDC. If this
input is not being used it needs to be
jumpered (Image 1.2.4).
1.2.5 Pressure Switches PS1
& PS2
The Pressure Switch inputs, PS1
& PS2, are generic digital inputs.
They can be used as sources for the
Shutdowns.
By default, they are acve when the
circuit is open but this can be changed
in the IO sengs. They are internally
pulled up to 5 VDC (Image 1.2.5).

1.2.11 BMS Module Valve
The BMS Module valve output is
intended to drive the ESD valve. It
has user-adjustable peak-and-hold
capability. The output voltage is the
same as POWER IN+. The maximum
current output is 2 amps (Image
1.2.11).
1.2.12 BMS Module
Thermocouple Inputs
TC1 & TC2
Thermocouple inputs TC1 &
TC2 accept a dual-probe k-type
thermocouple. They are not to be
used for separate thermocouples.
It can be used as a source for the
Processes and Shutdowns. It is
always used for the high-temperature
shutdown, TEMP LIMIT. If a dual-
probe thermocouple is not being
used, TC1 & TC2, individually, need to
be jumpered. (Image 1.2.12).

1.3 Applicaon Informaon
1.3.1 Alarm Output
The Alarm output indicates if the
system is in an abnormal state such as a
Shutdown or PILOT FAILURE. The output
behaves as a switch. By default, it is
closed when there is no alarm condion
but this can be changed in the IO
sengs. External alarm circuitry should
be limited to 50mA (Image 1.3.1).

2 System Overview
2.1 User Interface
The system user interface (Image 2.1.1) consists of a text display and seven keys (Table 2.1.1) that are used for menu
navigaon, selecng opons on menu items and entering or exing menus.
The text display provides informaon regarding menus, submenus, system modes, selectable opons, current mode
operaon states and alarms. The text display features automac shuto aer 60 seconds without user interacon
through the keypad. The automac shuto feature helps save power which is especially important in remote
installaons that are solar powered.
Pressing any key will wake up the text display and bring it to the top of the Main menu. If the STOP key is pressed while
the text display is o, it will both send the unit in to the STOPPED state and wake up the text display. Addionally, if the
system enters into any of the alarm states this will also wake up the text display and it will bring the alarm state screen.

2.5 System Modes
The system has two operaon modes, AUTOMATIC and MANUAL, to choose from. In AUTOMATIC mode (Image 2.5.1)
ignion is iniated by the user. Once the pilot is lit, the system will automacally start controlling the process and
aempt to relight the pilot if ame is lost. ON DEMAND mode is also available which only lights the pilot when ame is
required by a process. AUTOMATIC mode is the default system operaon mode.
In MANUAL mode (Image 2.5.2) the duraon of ignion is manually controlled by the user. Once the pilot is lit, the
user must iniate the process control. The system will not aempt to automacally relight if ame is lost. ON DEMAND
mode is not available in MANUAL mode operaon.
2.6 System States
Each system mode has mulple operaon states (Table 2.6.1 & 2.6.2) and alarm states (Table 2.6.3). The current
operaon state is displayed on the System Menu (Image 2.6.1). Upon power-up in AUTOMATIC mode, the system
inializes in the STOPPED state.
Note: An INDEPENDENT process runs independently of all other system states including alarm and shutdown states.
The INDEPENDENT process is only inacve in DIAGNOSTIC mode.

Table 2.6.1 · AUTOMATIC mode operaonal states
AUTOMATIC MODE OPERATIONAL STATES
STATE DISPLAY DESCRIPTION
STOPPED STOPPED
In the STOPPED state, the system closes all valves and acvates the ALARM output.
If ON DEMAND is disabled and the user iniates the system by pressing and holding
the OK buon for a second or more, the system will transion to the START-UP state.
If ON DEMAND is enabled and the user iniates the system by pressing and holding
the OK buon for a second or more, the system will transion to the IDLE state.
START-UP START-UP
In the START-UP state the system checks the input PS3 (PROOF OF CLOSURE). If the
input is acve then the system transions to the POC FAILURE state, if it is inacve
the system transions to the PRE-PURGE state.
PRE-PURGE PRE-PURGE
In the PRE-PURGE state, the system delays for the PREPURGE TIME before
transioning to the IGNITING state and the IGNITION RETRY(s) are reset. The PRE-
PURGE state is intended to provide me for the system to purge itself of unignited
gas.
IGNITE IGNITE
In the IGNITE state, the system begins ignion, opens the ESD and Pilot valves, and
then connues to ignite for the IGNITION TIME or unl ame is detected. If ame is
detected the system will transion to the ESTABLISHING PILOT state. If the ignion
me expires before ame is detected, then the system will transion to the PURGE
state.
PURGE PURGE
In the PURGE state, the system closes all valves. If there are IGNITITON RETRY(s)
remaining, the system delays for the PURGE TIME before transioning to the IGNITE
state. If there are no IGNITION RETRY(s) remaining, the system transions to the
WAIT state. The PURGE state is intended to provide me for the system to purge
itself of unignited gas.
WAIT WAIT
In the WAIT state, the system closes all valves. If there are WAIT RETRY(s) remaining,
the system delays for the WAIT TIME before transioning to the PRE-PURGE state. If
there are no WAIT RETRY(s) remaining, the system transions to the PILOT FAILURE
state.
ESTABLISH
PILOT EST PILOT
In the EST PILOT state, the system checks for the connuous presence of ame for
the PILOT EST TIME. If the ame is connuously present for the PILOT EST TIME, the
system transions to the PILOT ON state. If ame is lost during the PILOT EST TIME,
the system resets the IGNITION RETRY(s) and transions to the IGNITION state.
PILOT ON PILOT ON
In the PILOT ON state, the system will wait to transion to an ACTIVE state unl one
of the processes becomes acve. If ame is lost in the PILOT ON state, the system
resets the IGNITION RETRY(s) and transions to the IGNITION state.
IDLE IDLE
In the IDLE state, the system closes all valves and waits indenitely unl a process
becomes acve. If a process becomes acve, the system will transion to the START-
UP state.
ACTIVE 1 ACTIVE PRCS 1
In any of the ACTIVE states, the system connually checks the state of all processes.
If a process becomes acve, the system will open the process’ valve and update
the state name accordingly. If any process becomes inacve, the system will close
that process’ valve and update the state name accordingly. If all processes become
inacve, the system will transion back to the PILOT ON state if ON DEMAND is
disabled or to the IDLE state of ON DEMAND is enabled.

2.6.1 Shutdown States
Shutdowns stop the system if the system is in an ACTIVE,PILOT ON, or IDLE state and the user-dened condions of the
shutdown are met (Table 2.6.3). These allow for the system to be shut down for condions such as over-temperature,
over-pressure, high- or low-level limits, digital inputs, and more.

In the IGNITE state, if the user is sll holding the OK and → keys, the system begins
ignion, opens the ESD and Pilot valves, and then connues to ignite for up to 60
seconds or unl ame is detected. If ame is detected the system will transion
to the IDLE state. If the ignion me expires before ame is detected or the user
releases the OK and → keys, then the system will transion to the STOPPED state.
PILOT ON PILOT ON
In the PILOT ON state, the system will wait to transion to an ACTIVE state unl one
of the processes becomes acve. If pilot ame is lost, the system will transion to
the STOPPED state
IDLE IDLE
In the IDLE state, the system waits for the user to press the OK key in order to begin
the processes. If the user presses the OK key, the system will transion to the PILOT
ON state.
ACTIVE 1 ACTIVE PRCS 1
In any of the ACTIVE states, the system connually checks the state of all processes.
If a process becomes acve, the system will open the process’ valve and update
the state name accordingly. If any process becomes inacve, the system will close
that process’ valve and update the state name accordingly. If all processes become
inacve, the system will transion back to the PILOT ON state. If pilot ame is lost,
the system will transion to the STOPPED state.

SHUTDOWN STATE DESCRIPTION
SHUTDOWN 1 The system will enter a SHUTDOWN state if any of the SHUTDOWN(s) condions are met
while the system is in any of the ACTIVE,PILOT ON, or IDLE states. In the SHUTDOWN state,
the system closes all valves, except for the INDEPENDENT process, and acvates the ALARM
output. The system will remain in the ALARM state unl the user clears the alarm. The system
will transion to the STOPPED state once the alarm is cleared.

2.6.2 Alarm States
The system monitors various parameters for undesirable condions, some of which are congurable, and will enter an
ALARM state if those condions are met. This is to ensure proper operaon of the system and control of the processes.
Alarms and Shutdowns will stop the system processes if certain condions are met. Alarms stop the system, regardless
of what state it is in, if the permissive is acve, baery voltage is low, failure to light the pilot, proof of valve closure was
not proved, or the high temperature limit reached. Whereas shutdowns stop the system if the system is in an ACTIVE,
PILOT ON, or IDLE state and the user-dened condions of the shutdown are met.
In all alarm states the system closes all valves, except for the Independent process, and acvates the ALARM output.
The system will transion to the STOPPED state once all alarms are cleared.

ALARM STATE DESCRIPTION
PILOT FAILURE
The system will enter the PILOT FAILURE alarm state if it has not been able to establish pilot
ame and there is no IGNITION RETRY(s) and WAIT RETRY(s) remaining. The system will
remain in this state indenitely or unl the user clears the alarm.
PROOF OF CLOSURE
(POC) FAILURE
The system will enter the POC FAILURE alarm state if the PS3 input (PROOF OF CLOSURE)
is acve during the START-UP state. The system will remain in this state indenitely or unl
the user clears the alarm.
LOW BATTERY
The system will enter the LOW BATTERY alarm state if the voltage detected at the
BATTERY-IN input drops to or below the BATTERY LVD →LOW LEVEL. The system will
remain in this state indenitely or unl the voltage detected at the BATTERY-IN input
is at or above the BATTERY LVD →OK LEVEL and the user clears the alarm.
PERMISSIVE OPEN
The system connually monitors the (DIN) PERMISSIVE input. The system will enter the
PERMISSIVE OPEN alarm state if the permissive input becomes acve. The system will
remain in this state indenitely or unl the permissive input is no longer acve and the
user clears the alarm.
BMS FAULT
The BMS Module connually runs self-test to ensure its proper operaon. It connually
reports the status of these test to the ARControl.
The system will enter a BMS FAULT alarm state if the BMS Module has detected a lockout
condion or if the system stops receiving communicaon from the BMS Module. The
system will remain in this state unl the BMS Module lockout condion is remedied and the
user clears the alarm.
