| User Adjustable
Set Point - The user can set the LARC on site to trigger
over a wide range of flow rates. User sets the LARC to
react above, or below the set point. An LED indicates relay
status by lighting when the relay is energized. |
| HI-LO Range
feature - allows the LARC to be used with the 4000
Series Sensors (LO Range) or the 200 Series Sensors (HI
Range). |
| Form "C" Relay
Contacts - Rated 5 amps @ 125 VAC allow maximum flexibility
of control functions through both normally open, and normally
closed contacts. |
| Adjustable
Time Delay - User adjustable up to 100 sec. "ON" delay
before the relay triggers. This allows for normal surges
in flow rate to dampen out before the circuit is triggered. |
| Adjustable
Deadband - The user can adjust, in a range of flow
from 5% to 50% of the set point, between the points where
the relay is activated and deactivated. At the low end,
5%, this deadband prevents the LARC relay from chattering
if the flow rate stays at the set point. At the high end,
the deadband can act like an "OFF" delay to help
prevent pump cycling. |
| Latch Feature
- The user may choose to actuate an electronic latch
that will hold the LARC relay in an "energized" position
until manually reset. The reset operation requires the
user to acknowledge the LARC has reached an alarm point
by physically pushing an internal reset button or interrupting
the power supply. In the case of remote LARC installations,
the reset can be accomplished by momentarily turning off
the power supply to the LARC. The user may choose not to
actuate the latch feature for continual duty such as pump
motor control. |
| Variety of
Power Inputs - The LARC is designed to accept a variety
of power inputs, from 12-30 VAC or 12-40 VDC. The relay
contacts can be operated separately on voltages up to 250
VAC in addition the LARC circuit contains special transient
suppression safety features. |
