3. Wire the ground outputs.
Each relay is connected to a lamp to indicate an alarm level as
follows:
♦
Refer to Fig. 7 for wire-wrap pin locations and Figs. 2-6 for
examples of how the wiring can be done.
♦
Route the wiring through the large hole in the top of the dis-
play box.
♦
Wire the ground outputs from the relays of the MATs, SAAMs,
SAMs, or CPMs that will be critical alarms to the anode side
(side of diodes with numbers beside them) of the lowest num-
bered diodes on the top and middle PCBs. For example, 12 criti-
cal alarms can be wired to pins 1 through 6 on each PCB.
♦
Jumper the cathode (non-numbered) side of these diodes to-
gether.
♦
Wire one cathode to K1A on the bottom PCB.
♦
Wire the ground outputs from the relays of the MATs, SAAMs,
SAMs, or CPMs that will be major alarms to the anode side
(side of diodes with numbers beside them) of the middle diodes
on the top and middle PCBs.
♦
Jumper the cathode (non-numbered) side of these diodes to-
gether.
♦
Wire one cathode to K2A on the bottom PCB.
♦
Wire the ground outputs from the relays of the MATs, SAAMs,
SAMs, or CPMs that will be minor alarms to the anode side
(side of diodes with numbers beside them) of the lowest num-
bered diodes on the top and middle PCBs.
♦
Jumper the cathode (non-numbered) side of these diodes to-
gether.
♦
Wire one cathode to K3A on the bottom PCB.
♦
If you are using a 46029 CPM, install the relay jumper, on the
CPMs main board, in the IN position.
4. Wire relay pins to the battery.
♦
Wire relay pins K1B, K2B, and K3B to the battery (-48V) pin.
Terminals K1C, K2C, and K3C are used when additional resis-
tance is required in the operating path of the relays.
5. Wire the relay outputs, if needed.
♦
Wire pins 1, 2, and 3 of K1, K2, and K3 as needed for remote
alarm sending.
There are two pins labeled 500 ohms that are across a 500-ohm
resistor to provide optional strapping to limit the current of one of
the relay outputs, if required.
♦
Wire the resistor, if needed, in series with the relay output.
