Troubleshooting

P/N 151253 29

7.2 Trouble Conditions

Note:While Input 1 & 2 are activated, Input 1 & 2 will not open to indicate a trouble or supervisory condition.

Once the circuit is deactivated it will open to indicate a trouble or supervisory condition.

Trouble Condition What Happens

Low AC

(AC input voltage is low or off

for 6 hours or longer.)

Input 1 and Input 2 supervision circuits open after a 6 hour delay.

The green AC LED turns off as soon as low AC or loss of AC occurs (does not wait 6 hours).

The trouble relay is de-energized after a 6 hour delay.

The trouble restores within 1 minute of the AC voltage restoring to a normal level.

Low Battery

(Battery voltage is less than

21.4 VDC.)

Input 1 and Input 2 supervision circuits open. The yellow “BATT” LED lights.

The trouble relay is de-energized.

The trouble restores when battery voltage is greater than 22.4 VDC.

Earth Ground Fault

(The earth terminal is connected

to one of the positive or

negative terminals on the output

or auxiliary output circuits.)

Input 1 and Input 2 supervision circuits open. The yellow “FLT” LED lights.

The trouble relay is de-energized.

The trouble restores when the fault between the earth ground and one of the output circuit

terminals is removed.

Power Limit At AUX

(Current draw at the auxiliary

power terminals is exceeding

3.0 amps.)

Power disconnects at the AUX terminal. Input 1 and Input 2 supervision circuits open. The

yellow “AUX” LED lights. The trouble relay is de-energized.

The trouble restores when the overcurrent condition no longer exists. When a circuit goes into

a power limited state, it will reverse the polarity of the voltage at the terminals and verify the

load. If it is more than 1k ohms, the power limit will self-restore.

This does not automatically occur for some devices typically connected to auxiliary power.

Power limit conditions do not restore in reverse polarity monitoring if the devices are not

polarized (for example, some door holder devices). To allow automatic restores for

power-limited auxiliary circuits, it is recommended that all non-polarized devices be polarized

using a diode in series with each device.

Power-limited OUTPUT

(Current draw at an output

terminal is exceeding 3.0

amps.)

Power at the OUTPUT is disconnected. Input 1 and Input 2 supervision circuits open. The

corresponding yellow LED lights. The trouble relay is de-energized.

The trouble restores when the overcurrent condition no longer exists.

EOL supervision trouble

(Equivalent resistance of the

EOL resistor is outside the

range 2k - 10k.)

Input 1 and Input 2 supervision circuits open. Corresponding yellow LED lights.

The trouble relay is de-energized.

Trouble restores if an EOL within (2k-10k) appears at the output terminals.
