Item Controls and
Indicators
Description
1 Right arrow or Left
arrow
Selects the item being programmed by moving up or down.
2 STAND BY Enables and disables the gun output. When active (amber LED)disables all
channels. When inactive (green LED) all channels are permitted to run.
3
Up (increase) arrow or
Down (decrease) arrow
Increases or decreases the value of the selected parameter.
4 OUTPUT 1- 4 LEDs Illuminates when the selected gun output is activated.
5 CHANNEL SELECT Selects which channel is being programmed, observed or adjusted.
6 ENCODER LED Illuminates with each pulse from the encoder.
7 TRIGGER LED Illuminates when the selected trigger is On.
8 CHANNEL 1 - 4 LEDs Illuminates to indicate that the selected channel is being programmed,
observed or adjusted. The LEDs blink to indicate a warning condition.
9 PURGE Activates all outputs for active channel only.
NOTE: In flush mode it acts as an On/Off button. In purge mode it is a
momentary contact that is On when pressed and Off when released.

Setup menu screen Alphanumeric, 4 x 20 backlight LCD
- Cursor or asterisk (*) Appears beside a parameter to indicate that it is ready for setup.
- Hash (#) Appears at the top left of a page when a parameter has been changed. The
hash character disappears 10 seconds after the saving process.
