Initialization Mode
4-9
The starting time of your press is the time it takes for the crankshaft to start turning after the
DSV has been energized. Whenever the starting time exceeds the start time limit you set on
the Brake Monitor screen, SmartPAC 2 displays a “LOSS OF ROTATION DETECTED”
message (see page 7-3) and prevents the press from starting.
The stop time and start time limits set in Initialization are displayed on the Stop Time Status
screen in Run mode (see BRAKE MONITOR, page 6-19).
Calculating the Stop Time Limit
The value you set as the stop time limit on the Brake Monitor screen must factor in the normal
wear on your brake to prevent SmartPAC 2 from generating stop time faults when the
stopping time increases only a little. The stop time limit can be easily calculated based on the
actual stopping time of your press. To perform this calculation, do the following:
1.
Perform the Determining the Stopping Time of Your Press procedure in Run mode (see
page 6-20).
2.
Multiply the stopping time value you recorded in step 1 by 0.20 (i.e., 20%) for a new
brake or 0.10 (i.e., 10%) for an old brake, and add the result to the stopping time value.
This is your stop time limit.
Figure 4-6. Brake Monitor Screen
ADD 10% FOR OLD BRAKES, 20% FOR NEW BRAKES
The rule of thumb for calculating the stop time limit is to add 20% of the stopping time to
your press’s stopping time if your brakes are new, 10% if your brakes are old. Since
stopping time increases as the brake wears, the calculated stop time limit should be
roughly the same for both new and old brakes.
