Below is a list of frequently asked
questions regarding the servicing of Magtrol Motor Testing
Equipment. Should you need further assistance, contact Magtrol's
Repair and Calibration Department.
| Q |
How often should my
equipment be serviced/calibrated? |
| A |
Magtrol recommends that
all motor test equipment be serviced at least annually. |
| Q |
How long will I be without
my equipment if I send it in for service? |
| A |
The standard turnaround
time for repair/calibration is 10 working days or less.
We do offer an expedite service (3 days or less) for an
additional fee. |
| Q |
Can I have an outside
calibration house calibrate my Magtrol equipment instead
of sending it in to Magtrol? |
| A |
Magtrol does not recommend using outside calibration
houses for various reasons:
- Most on-site calibration houses will not have the
equipment necessary to properly calibrate all Magtrol
equipment to manufacturer's specifications.
- Magtrol offers complete service on dynamometers
which includes preventative maintenance such as bearing
replacement. Sending dynamometers in for routine maintenance/calibration
will help prevent costly repairs down the road.

| Q |
I just received my Magtrol
dynamometer back from service. But when I plug it in,
I have a high torque effect. What do I do? |
| A |
The first thing you need to do upon receiving a dynamometer
that has been serviced by Magtrol is to REMOVE THE SHIPPING
BOLT.
- Newer models HD-100 through HD-500: On dynamometers
with a framed cabinet, the shipping bolt is accessible
from the bottom of the base plate.
- HD-700 series: The shipping bolt is located
in the front pillow block just under the shaft.
- Older models HD-100 through HD-705: Remove
the top cover of the cabinet. Locate the gray colored
damper cylinder near the front panel. There is a damper
arm that runs between the damper cylinder and the
brake assembly. The shipping bolt is the long slotted
screw that extends through the damper arm and down
into the base plate.

| Q |
Is
there an alternative to using weights for on-site calibration
of large dynamometers like the WB/PB 15 Series?
(The large weights are difficult to handle.) |
| A |
A hydraulic cylinder with a reference load cell can
be used, but Magtrol does not provide it.
