STARTING PROCEDURE
Note:
It is necessary to connect a motor to load terminals; otherwise Shorted SCR or WRONG CONNECTION faults are
activated (OC or Wrong CON.). Other loads such as incandescent light bulbs, resistors, etc. may also cause an OC
or Wrong CON
. fault.
1 When mains voltage is connected to the ASTAT-XT, even if control voltage is
disconnected, full voltage may appear on the ASTAT-XT load terminals.
Therefore, for isolation purposes, it is necessary to connect an isolating
device upstream to the ASTAT-XT.
2 Power factor correction capacitors must not be installed on the load side of
the ASTAT-XT. When required, install capacitors on the line side of the ASTAT-
XT.
3 When using Inside Delta connection, wrong connection of the ASTAT-XT or
the motor may damage the motor; therefore please confirm that the motor is
connected properly!
4 Do not interchange line and load connections
5 Before starting the motor verify its rotation direction. If needed, disconnect
the rotor from the mechanical load and verify the correct direction of
rotation.
6 Prior to start up procedure, make sure that line voltage and control voltage
match the ones shown on the name plate of the ASTAT-XT.
WARNING
7 When the START signal is initiated and a motor is not connected to load
terminals, the SHORT SCR or WRONG CONNECTION (OC or Wrong
CON.
) protection will be activated.
