Startup Procedure; Operational Checks - Barnant Company 877-9605 Operating Manual

Startup Procedure

1. Check that all connections have been made as described in the
INSTALLATION Section.
2. Check that detectors are connected and properly positioned. Only one
detector can be connected to each channel. Use hook-and-loop fabric
fasteners to secure detector in position or, if permanent mounting is
desired, detector can be attached with #4 screws as described in the
INSTALLATION Section.
NOTE: Tubing may break at locations other than expected. Using a second
detector can provide for better detection.
3. If the audible alarm is to operate, set ALARM AUDIBLE switch to the ON
position. If no audible alarm is desired, place ALARM AUDIBLE switch in
the OFF position.
4. Set rear panel power OFF-ON switch to the ON position and check that
the front panel green POWER ON indicator is lit. The equipment should
now be operating normally.
5. If an alarm condition exists, proceed to the SENSITIVITY
ADJUSTMENT Section. If level detectors are used, they may need to be
inverted or rotated 180° for proper operation. The audible alarm can be
turned off by placing the ALARM AUDIBLE switch in the OFF position.
6. Perform the LIQUID-PAD Detector Sensitivity Check using drops of the
same liquid used in your application.

Operational Checks

LIQUID-SENSOR CONTROLLER
An operational check of the LIQUID-SENSOR Controller can be performed
using the ALARM TEST switch. This test should be performed only when
temporary transfer of power from the MAIN OUTPUT connector to the
AUXILIARY OUTPUT connector will not be disruptive.
Proceed as follows:
1. Set the ALARM AUDIBLE switch to ON for the audible alarm to be
activated or to OFF to deactivate the audible alarm.
2. Set power OFF-ON switch to ON position and check that POWER ON
indicator is illuminated.
3. Press and hold the ALARM TEST SWITCH. Check that the audible
alarm sounds (if activated), the ALARM ON indicator is illuminated, that
power shifts from the MAIN OUTPUT connector to the AUXILIARY
OUTPUT connector and that the CONTACT CLOSURE OUTPUT
activates any equipment connected to the output.
