4.2.3Setting the Digital Output Jumpers
Each digital output has an associated jumper to define its operation when power is interrupted and there is no battery backup to the board. This puts the Universal Monitor in a
The Universal Monitor comes from the factory with all digital output jumpers in the OFF position (nor- mally open). The jumper setting for each digital output can be changed to ON (normally closed). The settings are shown in Table 8.

To change the output jumper setting:
1.Find the respective black output jumper on the circuit board, as shown above.
2.Decide whether your configuration requires the jumper to be OFF or ON.
3.Set the jumper as needed:
•Set the jumper to OFF by placing the black jumper on the middle and top pins.
•Set the jumper to ON by placing the black jumper on the middle and bottom pins.

4.3Connecting Analog Inputs
The analog input connector blocks are at the bottom center of the Universal Monitor printed circuit board. The blocks are
To connect an input:
1.Turn OFF electrical power to the Universal Monitor.
2.If necessary, remove a conduit knockout to permit wire entry into the Universal Monitor enclosure.
3.Bring the wire(s) into the Universal Monitor enclosure through a conduit knockout or access slot.
4.Loosen the appropriate screw and slip the stripped end of the wire into the terminal block.
5.Tighten the screw until it holds the wire snugly.
