Off level enable / disable and Off level value through Modbus registers.
In Standalone mode
you control the parameters: Umax, Umin, Kick start / Soft start,
Off level enable / disable and Off level value by means of the hardware settings (DIP
switch, trimmers, jumpers).
In Normal mode
if Off level is disabled, Softstart / Kickstart is executed only once -
after the controller is supplied; otherwise Softstart / Kickstart is executed every
time the controller is switched on.
When

is selected, the controller receives a pulse control signal from the
remote control switch. When Logic mode is selected, the controller receives a pulse
control signal from the Ai input.
In both modes
Timer mode
and
Logic mode
the pulse width is to be more than 30
ms; otherwise the signal is filtered.
FRONT PANEL LED INDICATION
When the green LED on the front cover (
Fig. 10
) gives out a continuous light, the
controller operates in normal mode. When it blinks:

The red LED on the front cover (

it is on, the controller stops the motor. To restart operation after eliminating the
cause for overheating, disconnect the unit from the mains supply for a few seconds
and then connect it again.
