5 Line Interface Module LIM (only for
Integra 500)
The LIM is an external device that controls and monitors submersible
turbine pump (STP) activities by monitoring the input/output status of
the dispenser hook signals and STP relays.
Each Line Interface Module (LIM) (maximum of four (4) per system)
will monitor up to four (4) STP motors per module (for a total of 16
STPs per system). In the case of manifold submersible pumps, only
one (1) LLD sensor is installed, but the manifold will require one LIM
position for each submersible pump.
Typically, the dispenser sends a “hook signal” (110 VAC) to the
submersible pump controller. A LIM functions by intercepting this
hook signal and communicates via Petro-Net with the console. The
LIM sends a 110/220 signal to the STP controller to turn the
submersible pump ON, unless an alarm condition is detected, then
no signal is sent. An HV feedback signal confirms that the
submersible pump is turned ON.
The LIM works in conjunction with the console to test the lines during
periods of inactivity to constantly monitor the site for leaks in the
line(s).
5.1 LIM Specifications
5.2 LIM Installation
The LIM must be mounted on a wall using only the mounting holes
provided. Knockout locations are shown below. LIMs require
communication connection to the console and AC power.
NOTE: The LIM module is not NEMA-rated and must not be mounted
with direct exposure to the elements.
NOTE: Only use the knockouts provided. Seal all unused knockouts.
