same menu. The displayed value rolls over to “0” once the value “4294967295” 
(FFFFFFFFh) has been reached. To use this feature, the “C” (control) option must be 
installed and one of the PQMII switch inputs must be assigned to “Pulse Input 1(4)” 
function. The switch input will then count the number of closures or openings 
depending upon how the switch is conf igured; see 
Switch Inputs on page 5–21 for 
details. The minimum timing requirements are shown in FIGURE 6–2: Pulse Input

CHAPTER 6: MONITORING
The alarm messages appear only when the alarm threshold has been exceeded for the 
programmed time. When an alarm is assigned to an output relay, the relay can be set to be 
unlatched or latched. When the alarm is set as unlatched, it automatically resets when the 
alarm condition no longer exists. If the alarm is set as latched, a keypad reset or a serial 
port reset is required.
The 
SELF TEST ALARM occurs if a fault in the PQMII hardware is detected. This alarm is 
permanently assigned to the alarm output relay and is not user conf igurable. If this alarm 
is present , contact the GE Multilin Service Department .
