Digital Switch Wiring
ControlKeeper® 4A
Applying Power
1. After wiring is complete, make certain to clean panel
of all wire clippings and fragments ensuring that no
fragments get lodged between the circuit board and
enclosure.
2. Ensure that there are no loose wires or exposed wires
that could short out.
3. Power up the unit.
4. Please refer to the operation section of this instruction
for information on turning on and off lighting loads.
Refer to the Keeper Enterprise Software manual
for information regarding the programming of the
ControlKeeper 4A.
Relay Override Operation
The ControlKeeper 4A has two means of override located
on the logic board: individual relay override buttons and a
hardware override switch. It is possible to control lighting
loads and override programming using these override
mechanisms.
Figure 13: ControlKeeper 4A Override Mechanisms
Individual Relay Override Notes
Each relay on the ControlKeeper 4A may be overridden
using the individual relay override switches located on the
relay card on the right side of the enclosure. See Figure 13
for location of these switches. These override switches
will toggle the associated relay’s state with each push of
the button. This type of override is temporary in that the
override will last until the next command to the relay. This
override does not command the dimmers.
ALL OFF/AUTO/ALL ON Switch Notes
In addition to the individual relay override switch, there
is a hardware override switch that allows the override of
all relays on the board. If this switch is moved to the ALL
ON or ALL OFF position, all four relays will remain ON or
OFF as long as the switch is in that ALL ON or ALL OFF
position. The ON or OFF state is maintained regardless of
programmed state. In order for relays to run programmed
scheduling the hardware override switch must be in the
AUTO or center position. The dimmer channel will also be
overridden to full bright in the ALL ON position. See
Figure 13 for location of the hardware override switch.
LED Operation
The ControlKeeper 4A has LEDs for status monitoring.
These are explained below.
Figure 14: ControlKeeper-4A Status LEDs
Network LED:
The Network LED should flash only when activity is present
on the network wire. If communications commands are not
being transmitted over the network wire from the Keeper
Enterprise Software or broadcast switches and this LED
is flickering, ON constant, or flashing, it is an indication of
noise on the network wire that may interfere with proper
system operation. Please check all network wiring carefully
for shorts to AC Ground if this condition exists. Contact
Technical Support for further troubleshooting help.
Override Switch Indicator LEDs:
The Override Switch Indicator LEDs will be lit if the ALL
OFF/AUTO/ ALL ON Switch has been placed in the ALL ON
or ALL OFF position.
