File Select Mode
The File Select options are: Key Pad, Line Inputs, Flame Relay A-B and Modbus (Comms).
File Sel Mode=Key Pad indicates the file selection is made via keypad.
File Sel Mode=Line Inputs indicates the file selection is made via RFS 1 and RFS 2. Note : -2 models (e.g.,
95UVS4-2) only provide RFS1
File Sel Mode=Flame Relay A-B indicates File A is active until the flame relay is energized. Then File B is active
after the time delay as determined by setpoint AUTO FSLCT DELAY (See Config Menu). See Application Note on
page 41.
File Sel Mode=Modbus (Comms) indicates file selection is made via ModBus communication.
Learn Status
Status values can be MAN, ON, OFF, or BOTH. (see note)
MAN: Manual mode, no Learning done, or USER has changed at least ONE of the learned parameters.
ON:
Learn ON is done, OFF is not done.
OFF: Learn OFF is done, ON is not done.
BOTH: Both Learn ON and OFF have been done. (see note)
Note: If a user conducts both a Learn On and a Learn Off, then changes any value effecting the flame
calculations, the status will read MANUAL.
ModBus Comms
This screen indicates the remote communications address, baud rate, bits, parity, and stop bit. The address
can range from 1 to 247, as selected in the Config Menu. No two scanners in a communications loop should
have the same address. Default comm values are: “247 19200 8:N:1”, indicating address 247, 19200
baud, 8 bits, No parity, 1 stop bit.
Flame Relay Threshold
The flame relay has a factory programmed FLAME ON threshold of 40, and a FLAME OFF threshold of
20 (0-100 scale). Other ON and OFF thresholds may be programmed to suit particular applications.
On Threshold
Flame ON threshold (ON THRESH=xxx) This refers to the “pull-in” threshold of the internal Flame Relay
in terms of Flame Quality. The ON threshold can be set from 5 to 100. The ON threshold must be at least 5
units higher than the OFF threshold. When the flame quality is equal to or greater than the ON threshold
(for a time equal to the On Time Delay setting), the flame relay will energize. The On Threshold Factory
default is 40 (ON THRESH = 040)
Off Threshold
Flame OFF threshold (OFF THRESH = xxx). This refers to the “drop-out” threshold of the internal flame
relay in terms of Flame Quality. The OFF threshold can be set from 0 to 95. The OFF threshold must be at
least 5 units lower than the ON threshold. When the Flame Quality is equal to or less than the OFF threshold
(for a time equal to the Flame Failure Response Time setting), the flame relay will de-energize. The Off
Threshold Factory default is 20 (OFF THRESH = 020)
Software Revision
This displays the current internal software revision (eg: SW REV 0033:0010)” and Cyclic Redundancy
Check “CRC”.
