Before Applying Power
Prior to applying power to the MC-CPI board(s):
1. Disconnect all terminal connectors from the MC-CPI boards (I/O connections, internal
network and power connections (24V and COM terminals).
2. Apply power to the system.
3. Using a multimeter, check each of the wires to be connected to the MC-CPI boards as
follows:
•
Input circuits (switches, buttons, dry contacts)
: Using the VDC setting ref-
erenced to 1 bus (common), probe each input circuit. The reading should be either
24VDC or floating.
•
Output circuits (indicators, buzzers, chimes)
: Using the VDC setting refer-
enced to 1bus (common), probe each output circuit. The voltage reading should be
approximately 24VDC.
Caution
This system is designed for 24 VDC circuits only!
Do not connect 120 VAC or DC to any
terminal on the MC-CPI board.
Connect only the 24V power from connector J6 (24V
CUSTOMER LOAD SUPPLY) to the load (

and
Please refer to “Example: MC-CPI Wiring” on page 5-69
4. Power down the system.
5. Install the C-RJ11-CAN cable from J2 (Internal Network) on the MC-CPI board to the
MC-LSI (Landing System Interface board) in the cartop box.
6. Install the MC-CPI board I/O connections (I/O terminals).
7. Install the MC-CPI board power connections (24V and COM terminals).
Caution
To avoid damage to the MC-CPI boards, the system must be powered down before connect-
ing and disconnecting the MC-CPI board power connections (unplugging and plugging in
the 24V and COM terminals).
8. Apply power to the system and verify that:
• The MC-CPI board SPA indicator is ON (green).
• The relay closes and supplies 24VDC to the 24V CUSTOMER LOAD SUPPLY termi-
nals.
