Initial Control Settings
(Item numbers refer to and Figure 9: Opto-Electronics Module)
1.
Adjust all Pots to full counterclockwise (Items: 5, 9, 10).
2.
Set Climatic Compensation Selector Switch (Item 4) at 100X.
3.
Move the Gain/Setpoint Switch (Item 6) to Setpoint position.
4.
Verify the Setpoint Adjust Pot (Item 10) is set for 0.6 on analog meter (Item11).
5.
Move the Gain/Setpoint Switch (Item 6) to Gain position after step 4 is accomplished.
Note:
When first powered up, the instrument will show a Green LED on even when
no signal is present on meter. This occurs while the Delay circuit is charging and will
switch to Red LED (flame lost status) on, in approximately 2 seconds with the Delay
pot adjusted fully counterclockwise.
5.1.3
Delay Setting
The Delay setting postpones the Alarm condition once the set-point value is exceeded. This
can prevent false alarms from varying conditions or wind.
•
Once the instrument is aimed at the pilot flame and the Three-Way Switch is set to 100X,
adjust the Delay Pot (item 9) to achieve the desired delay response.
•
To verify settings, simply block the sight path by covering the Objective lens (item 8) and
time the delay for the red LED to turn on.
Note:
Full clockwise for maximum delay (approximately 2.0 minutes).
Full counterclockwise for minimum delay (approximately 2 seconds).
5.1.4
System Gain/Climate Compensation
Optimize these two gain settings by performing the following
(See Figure 9, Opto-Electronics module):
•
For System Gain, adjust item 5
•
For Climate Compensation, switch item 4
The purpose is to maximize the System Gain without observing excessive oscillation (noise)
on the analog meter.
5.1.5
Oscillation on the Analog Meter
Some minor fluctuations on the analog meter are acceptable as long as they do not /-.5
meter units.
Red/Green LED Indicators:
When the analog meter reading falls below the setpoint (0.6 on meter), the red LED “Flame Out
Alarm” will light after the delay has timed out. The green LED will go out.
