Digital Switch Wiring
ControlKeeper® 4A
Digital Switch LEDs:
These LEDs, labeled CAN-TX and CAN-RX, will flash when
Digital Switch information is being passed back and forth
between the Digital Switch Gateway and the ControlKeeper
4A.
Microprocessor Status LED:
The Status LED will flash ON and OFF continuously under
normal operation. The LED is an indication of microprocessor
health. If the LED is ON or OFF all the time, please use the
soft reset button on the controller. If the LED does not resume
normal flashing state, contact Technical Support.
Individual Relay Status LEDs:
Here are four relay status LEDs, one for each of the
relays on the ControlKeeper 4A. Please refer to Figure 14
for location of these LEDs. The relay status LEDs are an
indication of whether the associated relay is energized or
de-energized. If the relay LED is ON, the relay load should
be ON. If the relay LED is OFF, the relay load should be OFF.
Power LEDs:
This LED indicates that the ControlKeeper 4A is getting the
proper expected voltage from the transformer. If this LED is
not lit, there is a problem with power to the board. Please
contact Technical Support for further details.
Input Communications Status LED:
This LED indicates that the input chips are in normal
operation. These LEDs should flash to indicate system
normal status.
Relay Communications Status LED:
This LED indicates that the relay communications chips are
in normal operation. These LEDs should flash to indicate
system normal status.
ControlKeeper 4A RS232 Port
The ControlKeeper 4A has an on board RS232 port for
communications to peripheral accessory devices or to
the Keeper Enterprise Software. This RJ style jack should
not be connected to any device not intended for use with
the lighting control system. Connection to a phone line
will cause damage to the lighting control system that is
not covered under warranty. Please use only Greengate
approved device connections for connection to this port.
System Reset and Clear Commands
Under certain circumstances, you may want to reset the
ControlKeeper 4A. There are two different types of reset
commands available in the ControlKeeper 4A system: a soft
reset command and a clear reset command.
Soft Reset Command:
A soft reset command is used to initialize a new
panel address with the panel. If can also be used as a
troubleshooting technique if the panel is not responding or
to free up the microprocessor if the unit’s Microprocessor
Status LED is not flashing. The Soft Reset Command will
not cause loss of panel programming. To perform a Soft
Reset Command, press in and then immediately release
the reset button. (Refer to Figure 15 for location of the reset
switch.) When the reset button is pressed and released,
the status LED may hesitate briefly then resume normal
operation.
Reset Communications Switch:
In some situations it may be desirable to just cause a reset
to the input and relay communications chips. This can be
done using the reset button for this purpose in the middle
of the board. It is recommended that you contact Technical
Support prior to issuing this type of reset command.
Clear Settings Command:
A clear settings command is used to remove all
programming from a ControlKeeper 4A unit. It should be
done before downloading programming to the unit for
the first time or when asked to by a Technical Support
representative. Please use caution with this command!
When performing a Clear command, all relay loads will turn
off. Use the Hardware Override Switch to keep lighting
on if necessary. In order to reprogram the unit, you will
need to use the Keeper Enterprise Software. To perform
a Clear Command, press and hold down the reset button
(first button on left) while pressing and releasing the clear
button (middle button). Let go of the reset button. The
ControlKeeper 4A unit will be cleared of all programming.

Programming the ControlKeeper 4A
The ControlKeeper 4A is programmed using Keeper
Enterprise Software. Please refer to the Keeper Enterprise
Manual for programming details. Unless pre-programmed
by the factory, it is recommended that a Clear Command be
performed on the controller before the first programming
download to clear any test data that may be left in the
controller from factory testing.
