Hardware Set Up
The Remote Setpoint
Figure 4.2 shows the location of the remote setpoint jumper. The factory de-
fault is milliamp. Choose from the following settings:
V Remote setpoint with voltage signal (jumper removed)
MA Remote setpoint with milliamp signal (jumper installed)
Mechanical Relays
There are three output module sockets on the Power Supply Circuit Board, and
one output module on the Option Board (see Figure 4.2). The mechanical re-
lay on the Power Supply Board may be configured for either normally open (NO)
or normally closed (NC). A jumper located next to each socket determines this
configuration. All relay outputs are factory set to NO (normally open).
NOTE:
Changing the jumpers means
moving the jumper connector. The
jumper connector slips over the pins,
straddling two rows of pins. The
printed circuit boards are labeled
next to the jumpers.
