running are established.
3. Conditions that trigger upward peak running:
(1) MI = upward peak: When MI=59 (UPK) is ON, upward peaking running is enabled. When
MI=59 (UPK) is OFF, upward peaking running is disabled. When MI=59 is ON for any of the
elevators in group control operations, all elevators in group control enter upward peak
running mode.
(2) Upward peak hour 1: When time is currently between Pr.03-76 (Upward Peak 1 Begin) to
Pr.03-77 (Upward Peak 1 End), elevator executes upward peak running. This function is
determined by group control.
(3) Upward peak hour 2: When time is currently between Pr.03-80 (Upward Peak 2 Begin) to
Pr.03-81 (Upward Peak 2 End), elevator executes upward peak running. This function is
determined by group control.
(4) The number of starting with full-load for first main group control exceeds setting value:
If elevator starts at Pr.03-68 (First Main Group Control) with full-load, the number of
full-load increases by one until it reaches Pr.03-84 (Number of Full-load at Upward Peak).
On the contrary, it decreases by one until it reaches zero. When the number of full-load
reaches Pr.03-84, upward peak running is enabled. If you set Pr.03-84=0, upward peak
running is disabled. If the number of full-load is smaller than Pr.03-84 while upward peak
running is enabled, time starts to count and upward peak running is not disabled until time
reaches Pr.03-87 (Holding Time for Upward and Downward Peak). This function is
determined by group control.
 Downward peak running:
1. Goal: Shorten time that passengers wait elevators during lunch breaks or off-duty hour
2. Method: When in the mode of downward peak running, elevator automatically runs to
Pr.03-74 (Seven Main Group Control) after finishing running to floors below Pr.03-68 (First
Main Group Control). Elevator automatically runs to Pr.03-68 (First Main Group Control) after
finishing running to floors above Pr.03-74 (Seven Main Group Control) if Pr.03-90
(Automatically Runs Downward at Downward Peak) =1.
3. Conditions that trigger downward peak running:
(1) MI = downward peak: When MI=60 (DPK) is ON, downward peak running is enabled.
When MI=60 (DPK) is OFF, downward peak running is disabled. When MI=60 is ON for
any of the elevators in group control operations, all elevators in group control enter
downward peak running mode.
(2) Downward peak hour 1: When time is currently between Pr.03-78 (Downward Peak 1
Begin) to Pr.03-79 (Downward Peak 1 End), elevator executes downward peak running.
This function is determined by group control.
(3) Downward peak hour 2: When time is currently between Pr.03-82 (Downward Peak 2
Begin) to Pr.03-83 (Downward Peak 2 End), elevator executes downward peak running.
This function is determined by group control.
(4) The number of full-load when elevator runs downward and arrives at first main group
control exceeds setting value:
If elevator runs downward at Pr.03-68 (First Main Group Control) with full-load, the number
of full-load increases by one until it reaches Pr.03-85 (Number of Full-load at Downward
Peak). On the contrary, it decreases by one until it reaches zero. When the number of
full-load reaches Pr.03-85, downward peak running is enabled. If you set Pr.03-85=0,
downward peak running is disabled. If the number of full-load is smaller than Pr.03-85 while
downward peak running is enabled, time starts to count and downward peak running is not
disabled until time reaches Pr.03-87 (Holding Time for Upward and Downward Peak). This
function is determined by group control. Peak running at random floor has priority over
downward peak running.
(5) The number of downward hall calls exceeds setting value:
For hall calls from floors above Pr.03-68 (First Main Group Control), if the number of
downward calls is larger than or equal to Pr.03-86 (Number of Calls for Downward Peak),
and also larger than upward calls, downward peak running is enabled. If you set
Pr.03-86=0, downward peaking running is disabled. If the number of downward calls is
smaller than Pr.03-86 while downward peak running is enabled, time starts to count and
downward peak running is not disabled until time reaches Pr.03-87 (Holding Time for
Upward and Downward Peak). This function is determined by group control.
