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.
