Verify that the standard inputs connected to the Drive are properly
terminated and produce the desired operation. If an input does not
produce the desired result, remove power from the Drive and verify
the installation.
1.
Apply power to the Drive.
2.
Coast-to-Stop Input – With the Coast Stop input in its CLOSED
position (i.e. not in a coast stop condition) measure the voltage
present between terminals 7 and 8 of the regulator board
terminal strip. The measured voltage should be approximately
0V DC.
Repeat this procedure with the Coast-to-Stop input OPEN (i.e.
Drive in a Coast Stop condition). The measured voltage should
be 24V.
After proper operation is verified leave the Coast-to-Stop input
in its OPEN position (i.e. Coast-to-Stop the Drive).
!
ATTENTION: Failure to put the Drive in the
Coast-to-Stop condition could allow the Drive to
restart when performing the following checks. Failure
to observe this precaution could lead to personal injury
and/or equipment damage.
3.
Stop Input – Repeat step 2, measuring the voltage present
between terminals 1 and 3 of the regulator terminal board. The
voltage across the stop input should be 0VDC with the Stop
input CLOSED (Stop Not initiated), and 24VDC with the stop
input OPEN (stop initiated).
4.
Customer Interlock Input – The customer interlock input is a
permissive required to operate the Drive. It allows the Drive to
be interlocked with the driven equipment for personnel or
equipment safety purposes. If the Drive is stopped, it is
prevented from running until this input is CLOSED. If the
interlock input OPENS when the Drive is running, the AC
contactor will be forced open, and the motor will coast to a stop.
NOTE: If the application does not require a customer interlock,
verify the terminals 11 and 9 of the regulator board terminal strip
are jumpered, and proceed to Step 5.
Verify that the Customer interlock is operating properly by
repeating Step 2, measuring the voltage present between
terminals 11 and 9 of the regulator board terminal strip. The
voltage across the stop input should be 0V DC with the
Customer Interlock input CLOSED (permissive OK, and 24V
DC with the stop input OPEN (permissive lost).
