Relay Activation Type Set Incorrectly
The relay activation type is a key factor in determining when a relay activates. If this activation
type is set incorrectly, a relay may activate too soon or not at all. Refer to page 32 for details
on setting the correct activation type.
Panel Not Grounded
The touchscreen requires a ground connection to properly distinguish touch inputs on the
display. There is a grounding screw on the back of the hinged plate to easily connect the panel
to ground. When the panel is not grounded, the user may experience an unresponsive display
that does not react to inputs, or an extremely sensitive display that reacts to non-inputs.
Brasch strongly recommends that the control panel be grounded according to applicable wiring
codes. However, if this is not possible, using a stylus or otherwise ensuring that the touch
input is at the same potential as the floating ground will improve touch accuracy and
responsiveness.
Transmitter Mounted in an Unsatisfactory Location
For reliable operation, the transmitters must be mounted in the proper locations. Please read
“Mounting the Transmitters” on page 13 for guidelines on choosing locations.
Common mistakes include mounting a transmitter too close to a garage door. When the door
is open, rain may blow through the doorway and onto the transmitter housing. Another
common mistake is to mount the transmitter in a location where it comes in direct contact with
engine exhaust. The large amount of contaminates in engine exhaust can shorten the useful
life of the sensor.
One more common mistake is to choose a mounting location that places the transmitter too
near the outlet of air conditioners or heaters. Quick, drastic changes in ambient temperature
can cause erratic shifts in the sensor readings.
By following the mounting guidelines, many of the problems caused by improper mounting
locations can be eliminated.
