Designed as a display panel within supported MicroNet TMR control configurations.
Rear fiber-optic input points are marked RX and TX on the supplied unit.
Polarity markings are shown at the rear power terminals. Verify supply and wiring before energizing.
The physical keypad shown on the front panel supports local navigation and entry. Exact screen functions depend on the host application configuration.
No display: verify 24 VDC supply, polarity and terminal condition.
No host communication: check RX/TX fiber routing, connector cleanliness and seating.
Key response issue: confirm the host application screen and keypad mapping before replacing hardware.
Replacement mismatch: compare the full Woodward part number and label information, not appearance alone.
