COMMUNICATION
START PULSE
WIDTH
Certain functions of the auxiliary input are only started via a pulsed voltage
(see page 70). In this function, you enter the minimum pulse width to be
reached by the input pulse in order that the appropriate function is activated.
This ensures that the function is not activated by transient voltage peaks
(interference pulses).
Note!
This function is only available if the Promag electronics are fitted with the
communications module “RS 485” and if the auxiliary input is activated as
well as appropriately configured.
