Wiring the Std 0/4-20 mA Analog Output

The standard configuration of the flow transmitter includes two isolated 0/4-20 mA analog outputs (designated as
1 2
outputs and on the hardware, corresponding to outputs
may be made with standard twisted-pair wiring, but the current loop impedance for these circuits must not exceed
600 ohms. To wire the analog outputs, complete the following steps:
1. Disconnect the main power to the flowmeter and remove the enclosure #1 rear cover.
2. Install the required cable clamp in the chosen conduit hole on the side of the electronics enclosure.
3. Refer to Figure 20 on page xxxviii for the location of the J1 terminal block and wire the analog outputs as shown.
Secure the cable clamp.
WARNING!
4. If wiring of the unit has been completed, reinstall the rear cover on the enclosure and tighten the set screw.
After the Sentinel has been completely installed and wired, proceed to Chapter 2, Initial Setup, to program the
flowmeter.
WARNING!
