AC/DC MOV Backseat Relay Documentation
Firmware Version 4.0
Due to supply chain issues, a revision to the circuitry was needed for use with a different microprocessor and display. This provided the opportunity to design for use with both AC and DC MOVs in one relay by including a switched shunt resistor on the input.
- Revised hardware supports both AC and DC motors, depending on probes
- Signal input conversion increased from 10 bits to 12 bits for better resolution
- Add menu item to select AC or AC/DC probe
- Automatic detection of which phases have probe connected
- Delete probe sensitivity options menu. Standard sensitivity is 1 mA/A (AC) and 10 mV/A (AC/DC). The AC/DC probe should be used with small AC valves for best results.
- Delete key codes to select advanced menu display. Now the advanced menu screens show following a PREREQ Complete notification screen.
User's Manual, rev 2
Version 4.0 cannot be installed on 201602-AC and 201602-DC relays due to hardware differences. Contact Camp Creek Technolgies for upgrade options.
