Run-up Time Adjustment

TR1 can be used to change the run-up time between
8 and 60 min. The controller is factory set to 8 min.
If the gas load is large and the pump cannot reach the
nominal speed in the set time, the pump is stopped and
the controller gives Error 6 (Normal not reached at run-
up time). In this case, the run-up time setting can be
increased up to 60 min. by rotating TR1. The run-up
time can be read through the serial communication at
parameter 00700 (if protocol 1 is used) or at window
127 (if protocol 2 is used).
