Figure 2-8 Local Wiring Diagram
Wiring the Local Enclosure Configuration
Warning:
Ensure that all power is OFF before wiring any circuit.
This procedure is for instruments with the control circuit located in the sensing element enclosure.
1. Remove the control circuit from the terminal board socket by loosening the two thumbscrews on top of the transformer bracket. Note: the
screws are captive. Note the orientation of the control circuit. Grab hold of the transformer bracket where the screws are and unplug the
control circuit from the terminal board by pulling on the transformer bracket.
2. Install conduit between the local enclosure, disconnect device and the power source and monitoring circuit. Provide watertight hardware
and apply thread sealant to all connections to prevent water damage.
3. Refer to the Wiring Input Power section at the end of this section for the available input power configurations. Input power wiring
configurations are the same for local and remote enclosure options and also any output relay configuration. Wire in accordance with the
system requirements.
4. When connecting the relay wiring, do so with complete understanding of what the process requires of the instrument. The instrument
has dual SPDT or single DPDT relay output contacts dependent on the jumper configuration for each alarm switch point. For the relay
terminals and logic, refer to Figure 2-8. Also refer to Table 3-5 and Table 3-6 in Section 3 - Operation. Relay contacts are shown with the
relays de-energized.
