HOLD ONLY PRE-EMPT (MM-2-5-8-5)
PE INPUT 1 2 3 4 5 6
ON/OFF
PHASES
TIME
When ON hold only operation in effect, no sequence steps required. Only
holds phase if green when PE input active. Phases = one phase or a
compatible phase pair. Hold time range = 0 - 9.9 or 127 secs.
PE DELAY OPTION (MM-2-5-8-6)
PE INPUT 1 2 3 4 5 6
PED OMIT LAST X
VEH OMIT LAST X
Range = 0 - 9.9 or 127 secs. Used when there is delay before pre-empt.
Omits peds or phases during last x seconds of the delay period. Prevents
late service to non pre-empt peds or phases just before delay times out.
PRIORITY RETURN ENABLE (MM-2-5-8-7)
MODE ON/OFF: ON = Priority return Enabled
OFF = Priority return Disabled
SKIP OPTION ON/OFF: ON=Skip PE phase(s) 1st cycle after
PE if next after return ph. OFF=Don’t skip
PRIORITY RETURN PHASE MIN PERCENTS (MM-2-5-8-7-PgDn)
PHASE 1 2 3 4 5 6 7 8
PRA %
PRB %
PRC %
PRD %
Range: 0 - 100%. If “95” exit code used in sequence, will return back to
preempted phase (when PE started) if phase has demand & was served
less than above percent of its allocated time (max or coord split if auto-
calc percents loaded)
Note: When priority mode ON (above), clock ckts 66-68 select PRB-D
percent‘s. CKT 69 inhibits priority return operation.
PED PRIORITY RETURN MIN % (MM-2-5-8-7-PgDn 3 Times)
PHASE 1 2 3 4 5 6 7 8
PCL %
Range: 0 - 100%. If “95” exit code used in sequence, will return back to ped
of pre-empted phase (when PE started) if PED CLEAR was served less than
above percent of its normal ped clear time.

MEM = ON/OFF,
Ranges: MGR, WLK, PCL, OLY, OLR, OMT (Last X) = 0 - 9.9 or 127 secs
DEL = 0 - 255 secs, Re-service = 0 - 99 min.
Notes:
1. LPE starts at sequence step 10 (see sequence steps note)
2. OMT (Last X) & Re-service have same function as HI PE
