How to Wire a Honeywell UDA2182

Many industrial processes use instrumentation for monitoring a product's quality, such as water purification procedures. Water moving through filtration machinery must be checked repeatedly during the process for preventing poor final water quality. Honeywell offers an analyzer, under the model number UDA2182. This universal dual analyzer reports pH levels, conductivity and oxygen volumes within a specimen. However, this device must be wired properly for accurate readings on a consistent basis.

Things You'll Need

Screwdriver
Fused Disconnect Switch
14 gauge wiring

Instructions

- 1
  Open the analyzer's bezel case by removing the four retaining screws. Make sure that power is disconnected from the analyzer before opening the case.
- 2
  Release the printed wiring board retainer by loosening its two holding screws. Carefully slide the loosened retainer to the left to release the board.
- 3
  Pull the board halfway out of its retaining area. This position will allow easy wiring maneuverability.
- 4
  Insert a fused disconnect switch in the power line leading to the analyzer. The fuse should be 0.15 amperes for a 230 to 240 AC (alternating current) voltage supplied system. In contrast, a 110 to 120 AC voltage system should use a 0.30 amperage fuse.
- 5
  Move 14 gauge power wiring through the case's bottom wiring port. Attach the wiring to both L1 and L2/N terminals on the exposed board.
- 6
  Make sure to ground the power wiring with the green safety ground wire. Attach the green wire to a grounding stud within the analyzer's case.
- 7
  Connect any incoming inputs from electrodes to each individual terminal. Make sure that only one input connects to one terminal using 14 gauge wiring.
- 8
  Move the board back into its retaining area and close the case. Only apply power to the analyzer once the case bezel is closed for preventing electrocution.
