Troubleshooting
Symptom
Possible Cause
Corrective Action
Display is blank.
Fuse is blown.
No power to
monitor.
Monitor is
defective.
Measure voltage at pins 1 and 2 on monitor.
The voltage should nominally be 24 to 30 VAC.
If correct voltage is measured, internal monitor fuse is
probably blown. Unplug 10-pin connector from monitor
for 2 minutes. The internal fuse will automatically reset.
Plug unit back in and check display. If display is still
blank, check all wiring, etc. If no problems are found,
replace monitor.
If zero volts are measured, see
Wiring is incorrect. Check all wiring. If separate
transformer is not installed for each system, double
check polarity and for ground loops.
Verify circuit breaker is on.
Verify transformer primary measures 110 VAC.
Verify transformer secondary measures 24 to 30 VAC.
Verify voltage on pins 1 and 2 of monitor is 24 to 30
VAC.
If proper voltage is found between pins 1 and 2 of the
monitor, all wiring has been checked, fuses have been
reset, and screen is still blank, the monitor is probably
defective. Replace monitor.
Alarm relays
don't work.
Alarms are turned
off.
Incorrect wiring.
Relay may be
defective.
Press
LOW
or
HIGH
alarm key. The individual alarm set
points will display. If all alarm set points are zero, alarm
relay is not active, so relay will not be required to change
state.
Check the wiring from EverWatch monitor relay's output
to the device that is connected to the relay.
Disconnect the wiring from relay contact pins 7 and 8 for
low alarm relay and pins 3 and 4 for high alarm relay.
Connect an ohmmeter to relay terminals to verify contact
open and closes. Activate the alarm to manually trip the
relay. (This may require opening or closing sash). If
relay responds (contact opens and closes), the device
connected is incompatible or defective. If relay doesn’t
respond, relay is defective (may be caused by
incompatible device). Replace monitor.
"dATA Err"
flashing on
display.
Monitor was hit by
electrical
disturbance.
All data may be lost or changed. Review all configuration
parameters. dATA Err
is removed by pressing the
RESET
key.
