9.1 Profile
There are 4 programmable profiles.
• Normal Profile – Used under normal operating conditions.
• Inspection Profile – Used when the system is placed on Inspection/Access and
Construction operation.
• Emergency Power Profile – Used when the Emergency Power input is activated,
indicating the car is running on generator power.
• Short Profile – Used when the minimum short distance is set.
9.1.1 Adjusting S-Curve Profile
All four profiles are adjusted in the same manner. For the purpose of adjusting the S-Curve, the
Normal Profile is displayed.
9.1.1.1 Acceleration
The Acceleration parameter defines the rate at which the car reaches constant speed. The
higher the acceleration value, the sharper the rate. For example, with Contract Speed set at 350
fpm (5.8 ft/s), and Acceleration set to 2 fps
2
, the car will reach contract speed in 2.9 seconds
(this calculation does not allow for rounding). Each rounding corner will normally add about half
of its rounding time to the time required to reach contract speed.
NOTE: Divide fpm/s by 60 to get fps
2
.
The adjustment range is from 1-8 fps
2
.
• Default = 2 fps
2
• Units of measure = fps
2
The Acceleration parameter is also used to control the pattern ramp-up during relevel.
Changing this parameter will change the rate at which respective rated speeds are attained for
automatic run patterns and relevel patterns. A higher value will allow for higher speeds to be
attained up to contract speed.
The following procedure describes how to set Acceleration.
1. Navigate to MAIN MENU | SETUP | S-CURVE. See Figure 55.
2. From the S-CURVE menu, scroll and select the profile that is being adjusted.
