• DC In Terminal Strip. The DC in terminal strip is a 3-point terminal strip
located above the controller terminal strip (see Figure 1). It facilitates
wiring from the 12 VDC battery. The 50 foot battery cable is factory
wired to this terminal strip. Table 4 lists the function of each terminal.
Relays
The Rig Monitor includes four channel relays (two per channel) and three
common relays. Both sets of relays are single-pole, double-throw (SPDT)
and are rated for 10 amps at 250 VAC (resistive).
NOTE: You can select normally energized (NE) or normally de-energized
(NDE) settings for each channel in the Channel Control and Setup
program. This section describes the default setting: normally de-
energized.
The alarm 1 and alarm 2 common relays are factory-set as NDE
and the fail common relay is factory-set as NE. The alarm 1, alarm
2, and fail common relays’ NE/NDE settings are not user-
adjustable.
• Channel relays. The four channel relays are above the alarm terminal
strip (see Figure 1). These relays are dedicated to specific channels
and alarm levels.
For example, the channel 1, alarm 1 relay energizes if channel 1
recognizes an alarm 1 condition. Figure 5 below illustrates the
allocation of the channel relays.
