1.
The red (“Reset”) LED turns on and remains on for approximately 5 seconds. During this period
the MCB performs a self-test.
2.
The red LED turns off and the green (“Running”) LED turns on. This indicates that the
microprocessor has passed the self-test and is functioning properly.
3.
The amber (“Active”) LED remains off continually if no alarm conditions exist in the network. If
alarm conditions exist, the amber LED will flash as shown in Table 53.
If the above sequence does not occur after power is applied to the controller, there is a problem with
the MCB or its power supply.
Table 52 and Table 53 summarize the green, red, and amber status LED indications.

Keypad/LCD Display Connection
The MCB receives input commands and operating parameters from the keypad and sends requested
information to the display through the Keypad/LCD Display port via a plug-in ribbon cable.
Hex Switches
The MCB includes two hex (hexadecimal) switches that are used to set the network address.
The HI and LO hex switches are shown in Figure 37. A “hex switch setting” is defined as the HI
switch digit followed by the LO switch digit. For example, a hex switch setting of 2F would have the
HI switch set to “2” and the LO switch set to “F.”
Note:
You can change the setting of a hex switch with a 3/32-inch tip slotted-blade
screwdriver. If a hex switch setting is changed, power to the MCB must be cycled in order to
enter the new setting into memory. This can be done by turning the panel’s power switch off
and then back on.
