FUNCTIONAL DESCRIPTION
Valve Operation
•
Magnetic Safety Operator:
1.
Hold-In Current: </=150mA
2. Drop Out Current: 135-40mA
3.
Coil Resistance: 0.0155-Ohms +/-10%
•
Motor Operator: 4-pole step motor, 700mA consumption
• Sequencing:
1. Pilot Ignition:
-
Drive step motor - Push Magnetic Safety Operator
Open (physical stop at +600 steps; overdrive to
ensure pushing operator open).
-
Hold Magnetic Safety Operator open with power
from the control applied to the “V” terminal.
-
Drive step motor Steps - Open Secondary Pilot
Gas Passageway.
-
Emit Ignition Spark & Prove Pilot Fame, and then
remove power supplied by control from Magnetic
Safety Operator; power is now supplied to
Magnetic Safety Operator by thermocouple output.
2. Main Flame On (High):
-
Drive step motor– Calibrate step motor (physical
stop; overdrive to ensure “0” point calibration) and
open main gas flow.
-
Drive step motor– Move to High flame.
3. Continuously Variable Flame Modulation:
-
Step motor may be adjusted to any position
between High flame setting and Low flame setting
by either pressing and holding either the UP or
DOWN flame setting buttons on a transmitter
intended for use with this control.
4. Low Flame:
5. OFF: Drive step motor– Move to OFF setting.
SWITCH OPERATION
•
ON/OFF:
1. OFF Position (contacts open):
-
Control is idle waiting for ON/OFF switch state
change or command from wireless remote control.
2. ON Position (contacts closed):
-
Control will initiate the pilot ignition sequence.
-
Control will then default to Main Flame On (High)
Setting for 5-seconds.
-
Control will then read position of High/Low flame
setting switch and will proceed to that flame setting.
-
Control will ignore commands from RF circuit
(switch ON overrides remote control operation).
•
High/Low:
1.
Switch position is only read with ON/OFF switch in ON
position.
2. High Position (contacts closed): Control will operate step
motor on gas valve to Main Flame On (High) position.
3. Low Position (contacts open): Control will operate step
motor on gas valve to Low Flame position.
•
LEARN:
1.
Press and release to open LEARN window, the control
is ready to accept a transmitter security code.
2. LEARN window will remain open for 60-seconds.
3. Control will learn up to 3 different transmitter security codes.
4. Security codes will be retained in EEPROM memory
indefinitely if power is removed.
5. Press and hold for 6-seconds to clear all transmitter
security codes retained in memory.
AUDIBLE ALERTS
•
LEARN Window Open:
1. Audible Alert: Single long beep (~1 second in length)
after pushing the LEARN button.
2. Description of Alert: Inform the user that the module is
ready to learn the security code of a transmitter.
•
Code Accepted:
1. Audible Alert: Four short beeps (~0.2 seconds in length)
in rapid succession.
2. Description of Alert: Inform the user that the module has
successfully learned a transmitter’s security code.
•
LEARN Memory Cleared:
1. Audible Alert: Three long beeps in succession.
2. Description of Alert: Inform user that the transmitter
security code memory has been successfully cleared.
ERROR CODES
•
Ignition Safety (Protection for Ignition system):
1. Error Code: One short beep (~0.2 seconds in length)
every one-second.
2. Description of Fault: Pilot is not successfully ignited
within the trial period.
3. Action: The control will operate the step motor in the gas
valve to the OFF position.
4. How to Clear: Press OFF button.
•
Recycle Safety: (Protection for Unstable Pilot)
1. Error Code: Two short beeps every one-second.
2. Description of Fault:
-
Automatic Recycle - Pilot is proven and lost
3-times within 2-minutes without multiple ON/OFF
commands.
-
Manual Recycle – Ignition sequence is initiated
6-times within 2-minutes.
3. Action: The control will operate the step motor in the gas
valve to the OFF position.
4. How to Clear:
-
After 5-minutes has elapsed (5-minute internal timer
expires), the module must see the mode/switch in
the OFF position after that time.
-
Once the module see’s the mode/switch in the
OFF position after the 5-minutes has elapsed, it
will stop beeping.
-
Once the beeping has stopped, it will accept
normal operation including another ON command
from the user.
-
The only other way to reset this fault in another
manner is to remove power to the module (for
approximately 30-seconds until the internal circuits
discharge), and t
hen re-apply power.
