GUIDE TO CONTROLS
INSTALLATION
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 input(s) 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 manual. Polarity (neutral 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 1:
This 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, 100 mA power
supply (to be connected to the red wire of a Flowline sensor), and
(-) is the return path from the sensor (to be connected to the black
wire of a Flowline sensor). (S) is the Relay signal input to be con-
nected to the white wire with the Green wire returning to the (-)
terminal.
3/4" NPT Mounting Thread:
Installation of the compact relay controller takes advantage of the
3/4" NPT thread located on its base. This makes the controller fully
compatible with any of Flowline's level switches or Smart Trak™ or
Switch Pak™ mounting systems.
Always tighten the controller
from the wrench flat located
on the swivel base. Never
tighten from the body of the
controller.
Switch Cable:
When installing a Flowline flow switch,
adjust the cable away from the printed cir-
cuit boards in the controller body. Avoid
breaking the seal between the top of the
level switch and the plastic coated cable.
Connecting switches to input terminals:
Please note a difference between FLOWLINE flow switches. All flow
switches (models FT10-___5 and GT10-___5) will be wired with the
Red wire to the (+) terminal, the Black wire to the (-) terminal and the
White wire to the (S) terminal. See the illustration below to indicate
wiring for your switch. Note: the Shield wire will be used only for
long cable runs or where excessive electrical noise is present.
