Step Five
INSTALLATION
Switch Pak™, In-Tank Installation:
Flowline's Switch Pak™ mounting system is an in-tank fitting, which
enables users to install any technology, along the entire length of
track. Switch Pak™ may be installed thru the top wall of any tank or
flange, using a standard 2" NPT tank adapter or blind flange. If tank
top is not available, Flowline's side mount bracket, LM50-1001,
enables Switch Pak™ to be installed directly to the side wall or lip of
the tank.

1. Power indicator:
This green LED lights when AC power is ON.
2. Relay indicator:
This red LED will light whenever the con-
troller energizes the relay, in response to the proper condition at
the sensor inputs and after the time delay.
3. AC Power terminals:
Connection of 120 VAC power to the
controller. The setting may be changed to 240 VAC if desired.
This requires changing internal jumpers; this is covered in the
Installation section of the LC10/11 Series Manual. Polarity (neu-
tral and hot) does not matter.
4. Relay terminals (NC, C, NO):
Connect the device you wish to
control (pump, alarm etc.) to these terminals: supply to the COM
terminal, and the device to the NO or NC terminal as required.
The switched device should be a noninductive load of not more
than 10 amps; for reactive loads the current must be derated or
protection circuits used. When the red LED is ON and the relay
is in the energized state, the NO terminal will be closed and the
NC terminal will be open.
5. Invert switch:
This DIP switch reverses the logic of the relay
control in response to the sensor(s): conditions that used to ener-
gize the relay will make it turn off and vice versa.
6. Time Delay:
After the input(s) change(s) state, this control sets
a delay from 0.15 to 60 seconds before the relay will respond.
7. Input 1A indicator:
These amber LED will light immediately
whenever the appropriate sensor attached to the terminals detects
liquid, and will turn off when it is dry.
8. Input terminals:
Connect the wiring from the sensors to these
terminals. Note the polarity: (+) is a 13.5 VDC, 27 mA power
supply, and (-) is the return path from the sensor. If polarity is
reversed, the sensors will not work.
