Operation programming
Alarm output (4. SETTING: 2. ALARM)
Program alarm output behaviours of Time-up, Fast and Life alarms.
■ Time up alarm setting (Default: 20sec)
The LPC-1 controller outputs the time-up alarm to the user PLC and the TIME UP LED lights when either right
or left proximity switch does not detect the connecting plate within the set time. The signal output and LED
lightening continue unless the detection is made in time.
■ Fast alarm setting (Default: 140spm)
The LPC-1 controller outputs the fast alarm signal to the user PLC and the FAST LED lights at the fourth shots
after the pump speed has risen to the fast alarm speed or above. The signal output and LED lightening con-
tinue unless the pump speed falls below the fast alarm speed.
* The LPC-1 controller stops the pump at the third shots after the pump speed rises to the interlock speed (fast alarm
speed plus 10spm) or above. The controller performs teaching and speed compensation (see page 50) to keep the pump
speed below the interlock speed.
■ Life alarm setting (Default: 99,999,999 counts)
The LPC-1 controller outputs the life alarm signal to the user PLC and the LIFE LED lights when reciprocation
times (TOTAL COUNT1) exceeds the set number of times (max 999,999,999).
* Alarm output cancellation (see page 61) just turns off the LIFE LED temporarily. Reset the accumulated data in the TOTAL
COUNT1 before restarting operation, or the LED turns on again in operation. See
"Total number of pump shots confirma-
tion/cancellation"
on page 59 for detail.
