Flowline LC52 DataPoint - Manual (Page 4)

Step Four Step Five
INSTALLATION WIRING
Panel DIN Rail Mounting
The controller may be mounted by either a back panel using two
screws through mounting holes located at the corners of the controller
or by snapping the controller on 35 mm DIN Rail.
Wiring to Input Terminals
Signal input is always through the 24 VDC terminal.
The 28 VDC terminal is used as an alternative
power supply for three-wire devices. Please note a
difference between 2-wire and 3-wire level trans-
mitters and sourcing and sinking modes below.
Two-wire Transmitter Two-wire Transmitter
(Sourcing Mode / JWA) (Sinking Mode / JWB)
Three-wire Transmitter Three-wire Transmitter
(Sourcing Mode / JWA) (Sinking Mode / JWB)
Intrinsically Safe Two-wire Transmitter LU20-5001-IS
(Sinking Mode / JWB)
Note: Always install the controller in a location where it does not
come into contact with liquid.
Setting Input Polarity:
The LC52 can be set in one of two modes, sourcing and sinking. The
LC52 is shipped from the factory in the sourcing mode. This is compat-
ible with the LA12-_0_1, LA15-50_1, LP75-20_1, LU20-50_1, LU30-
50_4 and LU35-50_4 with no adjustment required. If using a LU30-
50_3, LU35-50_3 and LU20-50_1-IS, follow the instructions below.
1. Remove the back panel of the controller and gently slide the
printed circuit board (PCB) from the housing. Use caution when
removing the PCB.
2. Locate jumpers JWA and JWB on the PCB.
3. To change from sourcing to sinking, remove jumper from JWA
and place on JWB. The LC52 is shipped from the factory in the
sourcing mode (JWA active).
4. Gently return PCB into housing and replace back panel.
Note: Loop powered devices can operate in either the souring or sink-
ing modes. Please see step 4 for proper wiring instructions.
Changing from 120 to 240 VAC:
1. Remove the back panel of the controller and gently slide the printed
circuit board from the housing. Use caution when removing the
PCB.
2. Located jumpers JW1, JW2 and JW3 on the PCB.
3. To change to 240 VAC, remove jumpers from JW1 and JW2 and
place a single jumper across JW3. To change to 120 VAC, remove
jumper JW3 and place jumpers across JW1 and JW2.
4. Gently return PCB into housing and replace back panel.
120 VAC 240 VAC
Repeater Output:
The isolated repeater
output reproduces the
input current signal.
External power is
required and should
not exceed a maxi-
mum of 36 VDC.
