changing the monitor’s serial address or the clock settings, see “Configuration” on page 12.
Manually Resetting Relays
You can configure the 6666 and 6667 monitors so that you must manually reset the alarm
and System OK relays after an alarm. This feature is controlled by the LATCHED option on
the ATTRIBS submenu (page 23). To reset the alarm relays for a monitor, press and release
the RES button. The monitor displays the “LOCAL RELAY RESET” message, then returns
to the display page after resetting the relays.
Note: This resets the relays only if the input is no longer in alarm or the fault condition is
corrected.
