•
PTM is a single channel strain gage sensor input module to process the signal of the strain
gage to analog output.

Used for system setup or Job setup, capacity alarms are active, but
relay output is disabled. Calibrate mode will automatically be turned back
to peak after 5 minutes, incase accidently left in calibrate.
•
Peak Mode –
Used after calibration is complete for standard tonnage monitoring
operations. Capacity alarms and relays are active.
ALARMS
In normal operation, the Alarm relay is closed for fail safe. When the tonnage alarm(s)
condition is detected, the system opens the TOP STOP relay
•
High/Low Capacity –
Normally set at machine capacity. This provides the protection for
the Machine. This alarm is active in all modes.
