(C4) RLF2 Cancel Option (PROM item - RLF2_CANCEL_RLF1)

This byte contains one bit for each RLM group:-

Bit 7 Bit 6 ... Bit 1 Bit 0

Group 7 Group 6 ... Group 1 Group 0

0 = RLF2 has no effect on RLF1.

1 = When RLF2 is activated, any phase appearance delays due to

RLF1 on this RLM group are cancelled.

(C5) Switch off/inhibit Option (PROM item - RLF2_SWITCH_OFF)

This byte contains one bit for each RLM group:-

Bit 7 Bit 6 ... Bit 1 Bit 0

Group 7 Group 6 ... Group 1 Group 0

0 = When phases are inhibited by RLF2, the phases display red.

1 = When phases are inhibited by RLF2, the phases are switched off

(i.e. blackout). This option is used for part-time signals and care

must be taken when configuring to ensure that all phases on a

stream are blacked out.

(C6) RLM Latching Option (PROM item - LATCHED_RLMS)

This word contains two bits for each RLM group and each bit pair selects latching or

non-latching operation for RLF1 and RLF2:-

... Bit 3Bit 2Bit 1Bit 0

... Group 1

RLF2

Group 1

RLF1

Group 0

RLF2

Group 0

RLF1

‘Even’ bits: 0 = The effect of RLF1 is removed when the faulty lamp is replaced.

1 = A manual reset is required to clear RLF1.

‘Odd’ bits: 0 = The effect of RLF2 is removed when the faulty lamps are

replaced (assuming the signals have not been switched off).

1 = A manual reset is required to clear RLF2.

Note that for a part-time controller, RLF2 should be configured as non-latching as the

latching effect is achieved in the RLM unit since the lamps are switched off.
