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.
10 SETUP backward Scrolls backward through the setup screens.
11 SETUP forward Scrolls forward through the setup screens.

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.
