Shorted SCR Alarm
The Watlow DIN-A-MITE alarm option provides an alarm output for shorted SCR conditions. A shorted SCR alarm is detected
when there is no command signal and a load current is detected. The alarm output is then energized.
This is a non-latching
alarm.
Torque Procedure
1. While connecting the line and load wires, ensure that all wire strands are inside the connector.
Do not allow loose wire
strands to hang out of the connector
. Once you have installed the wire, torque these same connections to 9.0 to 10.1 Nm
(80 to 90 in-lb). Use a dial or digital-type torque wrench and hold the torque at 9.0 to 10.1 Nm (80 to 90 in-lb) for 30 seconds.
The 30-second hold allows the wire to settle, minimizing the wire cold flow.
2. Re-torque the same connections after 48 hours.
3. Develop a maintenance program to re-torque all load and line connections every three to six months.
NOTE: L1 and L2 terminals are 3/16-inch Allen head screws.
