Indicators
The LED indicators on the lighting controller and their
functions are listed in Table 2.
LED Function Description
Network
(Ethernet)
Ethernet Communication Status
Indicators LNK and ACT
One LED (LNK) turns on to indicate a cable link is successfully
established, and another green LED (ACT) flashes to indicate
network activity (incoming or outgoing data) on the port.
Power Device Power Indicator
This amber LED is lit when control power is present on the device.
If no control power transformer is connected, the LED is off.
Scan CPU Scan Indicator
This red LED flashes at a rate relative to the CPU scan rate of the
database within the controller.
Network
(NET1)
RS-485 Communication Status
Indicators for NET1
A green LED flashes to indicate when the device is transmitting
out the associated port and a red LED flashes to indicate when
the device is receiving data through the port.
Network
(NET2)
RS-485 Communication Status
Indicators for NET2
A green LED flashes to indicate when the device is transmitting
out the associated port and a red LED flashes to indicate when
the device is receiving data through the port.
Alarm Output
(BO68)
Output Status Indicator
If the output is activated, a green LED is lit. If the output is not
activated, the LED is off.

Panel Mounting Switch
The panel-mounting switch, illustrated in Figure 5,
provides the ability to mount the circuit breaker panel
“Service from top” or “Service from bottom.” If the panel
is mounted right-side up (the connectors along the
bottom of the board), the switch should be set to
NORM
(default). If the panel is mounted upside down (the
connectors along the top of the board), the switch should
be set to
FLIP . This insures correct breaker addressing.
This switch is located near the NET2 connector.

Jumpers
This section describes the jumper settings on the lighting
controller.
Input Signal Type Jumper
The input type is selected by placing the jumper,
illustrated in Figure 6, in the correct location on the Input
Type Selector Block. The figure shows the factory default
selection of 10 k
Ω.
• 4–20 mA – for sensors that output a 4–20 mA signal
• 10K – Internally powered for resistance and dry
contact measurement.
• 5V – For sensors that output a 0–5 Vdc signal
• 10V – For sensors that output a 0–10 Vdc signal

SRAM Memory Clear Jumper
This jumper, illustrated in Figure 7, is provided to clear
the controller database (SRAM). The two positions
function as follows:
• RUN – The battery is connected in the circuit and
maintains SRAM memory, even when 24 Vac power is
removed from the controller, thereby maintaining
both the integrity of the database and the internal
time of the on-board real-time clock (for as long as
the battery lasts). This jumper position is required
before applying power for the device to operate
properly.
• CLEAR – When the jumper is moved to the CLEAR
position (only when the power is off), the SRAM
memory is cleared, deleting the database but not
resetting the internal time of the on-board real-time
clock. This jumper position is recommended if the
product will be stored for prolonged periods. The
database will be loaded from flash memory.

Device Type Jumper
This jumper, illustrated in Figure 8, configures the
lighting controller as one of several device types,
