Relay Override Operation

ControlKeeper® TouchScreen Logic Board

4.  Plug the communications cable (red CAT5 Cable 

provided) into the Relay Stack Controller Card (RSC) 

located at the bottom of the enclosure. This cable can 

be plugged into either of the two RJ45 jacks located on 

this board. See Figure 8 below.

5.  If lighting needs to be ON during the next steps, make 

certain that the RSC override switch has been used to 

override the lighting ALL ON. Press the Reset button 

located in the upper left corner of the logic panel. 

This will initialize a system reset, causing the relays to 

assume to panel’s state. (If unit is being powered for 

the first time without being programmed, the relays 

will turn OFF unless the RSC override switch is used to 

override lighting ALL ON prior to the reset being hit.)

Relay Override Operation

The ControlKeeper T has two means of overriding relays 

ON or OFF without the need of the logic board in place. 

First, there are individual relay override buttons for each 

relay located on the relay hardware. Second, there is an 

all enclosure override switch located at the bottom of 

the enclosure. It is possible to control lighting loads and 

override programming using these override mechanisms 

without the logic board being in place.

Individual Relay Override Notes

The individual relay overrides are located in the high voltage 

section of the controller. If you are not an electrician, or 

rated for work in a high voltage environment, it is not 

recommended that you access these switches from a 

safety concern.
Each relay on the ControlKeeper T may be overridden using 

the individual relay override switches located at the top 

left of the low voltage section. See Figure 10 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 that the relay is given.
