Message
When RECR (input1) is Up and TPR1 (input2), TPR2
(input3) are Down, TPR3 (input4) is Up and time

difference between TPR2 Down (triggering) and TPR3 S1 SPAD at adv str
48 SPAD at Adv Str without
Up is more than time T1, and the time difference SC without shunt
Shunt Permission
between TPR2 Down and RECR Up is more than the permission
given time interval T1, TPR2 is continuously Down for
T2., SHKR Up status considered in extra variable.

51 TFR Relay Stuckup IF TFR IS PICKED UP THEN IT IS TFR RELAY STUCKUP. MM
If Buttons (GNR, UNR) are pressed in wrong
S1-S2 Wrong
52 Wrong Operation combination Then it is WRONG OPERATION. Both are MM Operation
triggering signals.
At the time of Point zone track (input1) Up, if Platform
track (input2) Down, Before Point zone track (input3)
Up and after time interval if G(R)LR (input4) is Up then S1-S2 Route not
53 Route not Released RDSO MM
Check the following. Backlock tracks are in Up state and Released
G(R)LR is Up. If any of above relays are not in required
state then it is Fault. Point zone track is triggering.

Note: (i) RDSO Latest guidelines to be followed
(ii) User may define & configure some more Logics as per Specific need
