5.3.2 Logic: Features
The GCE MCF provides various logic capability features. Figure 5-15 selecting these features.
•
ANDs Used controls whether the Logic: AND 2- 8 menu options are available
•
Ors Used controls whether the Logic: OR 1 – 4 menu options are available
•
Equations Used controls whether the Logic: Equation 1-10 menu options are available
•
User Timer controls whether the Logic: User Timers menu options are available and
whether the User Timer 1-10 options show up in the
System Inputs, System Output
and
System I/O
list.
•
Switch Inputs Used controls whether the NWP 1-4 and RWP 1-4 options show up in the
System Inputs
, Output and I/O list.
•
General I/O Used controls whether the General IP 1 – 16 and General OP 1- 8 option
show up in the
System Inputs, System Output
and
System I/O
list.
•
Maint Call Rpt I/O Used controls whether the Maint Call Rpt IP and Maint Call OP show
up in
System Inputs, System Output
and
System I/O
list. The Maint Call OP repeats the
state of the Maintenance call output on the chassis. The Maint Call Rpt IP provides a
way of providing an external input or extra logical control via internal logic that can drop
the maintenance call output. If the Maint Call Rpt I/O Used is set to yes, the Maint Call
Rpt IP must be set to TRUE if not used. This can be done via an internal channel, for
example:
o
Int.1 Sets Maint Call Rpt IP
o
Int.1 Set by TRUE
•
Emergency Activate IP can be set to yes to provide an Emergency Activate input that
can be mapped to an external vital input. When this input is de-energized it will override
all wraps and out of service conditions and de-energize all outputs and activate the
crossing.
