Installation Guide
- Mount the module on the compatible Honeywell terminal base.
- Set the keyswitch to position 2.
- Use shielded multicore cable with one shield per channel.
- Keep channel isolation above 500 V.
- Confirm lead resistance stays below 10 ohms per lead.
- Install IP54 or better housing for field use.
Commissioning and Maintenance
Set input type and range per channel group. Choose 2-, 3-, or 4-wire RTD mode. Enable fault detection to catch broken leads or shorts. Use the overrange and underrange alarms for early warnings. The 4 ms response supports fast control loops. Oiltech Controls verifies each module before shipment. Contact info@oiltechcontrols.com for setup help.
