Operating Manual
50
The startup condition of the generator
must be programmed with the
configurations of auxiliary contact 1. The
startup is carried out by first activating
the operational contact and then
activating the startup contact. The latter
engages several times, if necessary, to
start up the motor. If a voltage appears at
the terminals of AC In, the startup
contact is released.
A.
Main contact hold/interrupt time
{1574}
B.
Time before a starter pulse {1494}}
C.
Starter pulse (with AUX2) {1492}
D.
Number of starting attempts {1493}
8.1.2.1.1
Generator control {1491}
Activates the combination of the two auxiliary contacts for the generator start and the
management of the start impulses.
8.1.2.1.2 Number of starting attempts {1493}
The start contact is activated a limited number of times in order to protect the starter
if the generator has a fault. Once the maximum number of start has been reached,
the operational contact is also deactivated. For a new attempt to be made the
condition that generated the start must disappear and reappear.
8.1.2.1.3 Starter pulse (with AUX2) {1492}
With this configuration you can adjust the time at which the start contact is activated.
8.1.2.1.4 Time before a starter pulse {1494}
This configuration determines the duration between the start attempts. It also
determines the duration between the activation of the operational contact and the first
attempt at restarting.
8.1.2.1.5 Main contact hold/interrupt time {1574}
Some generators must have the main contact completely stopped between the
cranking attempts (choke pulse). This parameter allows to set this duration.
