OTHER FEATURES
•
Jobs Recipe
– You create alarm settings per job base and store to Job Recipe for later
quick download to setup the system.
•
Password Protection
– The setup screen is password protected to insure only
appropriate personnel can bypass the alarms (switch to calibrate more) or change the
scale set point.
USER CONNECTIONS
Refer to page 12 for the user connections drawing.
CUSTOMER SUPPLIED POWER
A Precut hole has been provided to connect conduit for customer supplied power.
•
120VAC
– Connect to the 3Amp Circuit Breaker
•
AC Neutral
– Connect to the Neutral Terminal.
(Neutral should be grounded at the
transformer to prevent floating ground)
•
GND
– Connect to Ground.
CAM INPUT
The provided CAM INPUT relay is a 24VDC relay, and can either be triggered by customer
pr24VDC and DC common, or Use the supplied DC1 (+24VDC) through a dry contact to
A1 and connect DC2 (0VDC) to A2. This input can be triggered with a proximity switch or a PLC
output. This input is the “look window” for the tonnage monitor.
•
A1
– +24VDC signal.
•
A2
– 0VDC signal.
HIGH/LOW CAPACITY FAULT RELAY OUTPUT
The provided relay output is programmed to be energized unless a fault occurs; this is considered
“Fail Safe”. If a relay output turns off, a fault has occurred, and will commonly trigger a top stop.
•
11
– Customer supplied Signal
•
12
– Normally Closed Output, this is the typical not used.
•
14
– Normally Open Output, this is the typical connection point for an alarm signal, and is
commonly connected with the presses TOP STOP circuit.
STRAIN GAGE INPUT
The drawing on page 10 shows the proper wiring for a strain gage to the PTM.
The strain gage
wiring should not be ran within 12” of any high voltage, (60V or above), if necessary wires
should cross perpendicular to insure the least amount of noise transference.
