Jumper Configurations; Run-Up Time Adjustment - Agilent Technologies TwisTorr 74 FS PCB 24 Manual De Instrucciones

Jumper Configurations

The following figures show the configuration and meaning of the
individual jumpers on the board.
Jumper W7 is used to select the data exchange rate, as shown in the
figure.
Figure 4
Jumper W6 is used to set the Soft Start, as shown in the figure.
Figure 5
The W5 jumper is just for factory setting and must not be moved.

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).
