Basic Operation
This section describes the day-to-day operations for the 6687 protection monitor. It includes
the steps to use the display backlight, display alternate pages, reset the relays after an alarm
(if the alarm relays are set to latching), and display the firmware version. It also describes
the status messages that may appear on the display.
Display Backlight
The backlight makes it easy to see the 6687 display, even in dim light. When the system is
functioning properly and no signals are in alarm, the backlight is off. However, in case of an
alarm or transducer failure, the 6687 automatically turns on the backlight to alert you.
To turn on the backlight, press and release the LIT button. The backlight remains on for
about 3 minutes, after which it automatically turns off. If you press and hold the LIT button
for 5 seconds, the backlight remains on for 10 minutes.
You can manually turn off the backlight by pressing the LIT button once. Note that if the
backlight is on because of a fault condition, you cannot turn it off until the fault or alarm
condition is corrected. If the alarm relays are set to latching (LATCHED option, page 22),
you must also reset the alarm relays with the RES button before the backlight turns off.
