4200 Transmitters

July 2013

DC power supply independent of the receiving device is recommended. A separate return is required for the relays.

This prevents relay return currents from flowing in the transmitter 4 to 20 milliamperes DC current loop.

For the position switch relay wiring, during normal operating conditions relays K1 and K2 are energized, which

connects the common (C) terminal to the normally open (NO) terminal (TB1 and TB2, figure 4). During a tripped (or

alarm) condition the relay is de‐energized, which connects the C terminal to the normally closed (NC) terminal. If

power is removed or lost from the power supply both relays are de‐energized which connects the common (C)

terminals to the normally closed terminals (NC).

CAUTION

Connect the transmitter grounding terminal (key 58) to an earth ground. Improper grounding of the position transmitter

can cause erratic operation.

Before making transmitter or position switch connections, ensure that the power supply is turned off. Refer to figure 4

for location of connections.

1. Remove the cover from the field wiring compartment. Note that you will need to loosen the set screw (key 106)

before removing the cover.

2. Bring the transmitter field wiring and/or position switch wiring into the housing through one or both of the ports.

3. Field wiring connections:

Note

On transmitters with position switches, always make the connection between the power supply negative (-) terminal and the (R)

terminal on TB3, even if the position switch outputs are not used.

a. For a 4210, 4215, or 4220 transmitter with position switches, connect a wire from the (-) terminal of the power

supply to the (R) terminal on TB3. Also connect a wire from the (-) terminal on the power supply to the negative

(-) terminal of the receiving device. Connect a wire from the receiving device positive (+) terminal to the (-)

terminal on TB3. Connect a wire from the (+) terminal on the power supply to the (+) terminal on TB3. Provide

wiring for the position switch indicating device to match the application.

b. For 4212 and 4222 position switches without a transmitter, connect a wire from the (+) terminal of the power

supply to the (+) terminal on TB3. Connect a wire from the (-) terminal of the power supply to the (R) terminal on

TB3. Provide wiring for the position switch indicating device to match the application.

c. For a 4211 or 4221 transmitter without position switches. Connect a wire from the (+) terminal of the power

supply to the (+) terminal on the barrier strip (key 11). Connect a wire from the (-) terminal of the power supply

to the negative (-) terminal of the receiving device. Connect a wire from the receiving device positive (+) terminal

to the (-) terminal on the barrier strip.

4. Connect the grounding terminal (key 58) to an earth ground.

5. For a 4210, 4212, 4215, 4220, or 4222 instrument with position switches, perform the following steps to connect

the position switch wiring:

a. Connect the high position switch field wiring from the high indicating device to TB1 on the field circuit printed

wiring board.

b. Connect the low position switch field wiring from the low indicating device to TB2 on the field circuit printed

wiring board.
