6.1.6 Standby speed setting
The pump can be run at standby speed rather than full rotational speed. The standby
speed is a user-configurable option and can be set to any value between 55% and 100%
full rotational speed.
When the pump is shipped, it is configured with a standby speed of 70% full rotational
speed.
The standby speed setting can be changed using the STDBY+ and STDBY- push buttons
located on the motor controller (shown in Figure Controller view on page 70 ) or by using
a serial command. If using the buttons, each button press will adjust the speed by 15 Hz
(1%).
To change the standby speed setting using a serial command, send the following
command (where the characters 'd' represent the value as a percentage of full rotational
speed):
