UX-258TH FO-475TH 2. Description 2-1. Relay board unit 1. Remove the TEL/LIU PWB, control PWB and Power Supply PWB from this unit, and mount the relay board unit instead. • Before connecting the wiring to the relay board unit, set the test PWB switches to the fixed position. 2. The setting is as follows. • The relay cables are used as one pair. • The sensor is wired as shown in the following figure. • The door swich and hook switch are manually operated.
UX-258TH FO-475TH 3. Shading paper The white and black basis is applied to remember the shading waveform. Be sure to perform this operation when replacing the battery or replacing the control PWB. Execute in the shading mode of DIAG mode.
