Description - Barnant Company 877-9605 Operating Manual

DESCRIPTION

The LIQUID-SENSOR Controller, shown in Figure 6, is used to monitor
various liquid detector devices. When an alarm condition is detected, the
controller deactivates the rear panel MAIN OUTPUT power connector and
supplies power to the AUXILIARY OUTPUT power connector. Also, when the
alarm condition is detected, a contact closure output is provided at the rear
panel CONTACT CLOSURE OUTPUT connector (a 1/8-inch phone-type
connector) for activating remote devices such as an Environment Monitor or
a second pump drive. The fault condition is indicated by a red ALARM ON
indicator on the front panel and by an audible alarm (unless the ALARM
AUDIBLE switch has been set to OFF).

The MAIN and AUXILIARY connectors, shown in Figures 7 and 8, are used to
connect to external devices such as pumps. The pump connected to the
MAIN OUTPUT connector will operate when no alarm condition exists. When
an alarm condition is detected, power to the MAIN OUTPUT connector is
turned off and power is applied to the AUXILIARY OUTPUT connector. Thus,
if no pump is connected to the AUXILIARY OUTPUT connector, pumping will
cease. If a pump is connected to the AUXILIARY OUTPUT connector, that
pump will be turned on. The switch over occurs within one second after
detection of an alarm condition.
