Service Philosophy
Servicing is supported at three levels by Vinten Inc. after the warranty period
expires:
• On-site service may be contracted from Vinten Inc. or through the
local representative from which the system was purchased.
• Board-level replacement may be readily accomplished by station
personnel, using stocked or ordered circuit boards.
• Component level replacement is feasible to some extent, by quali-
fied station engineers or technicians, using the material in this
chapter.
Service questions may be directed to factory service specialists at Vinten Inc. in
Valley Cottage, NY, by phone at 1-
845-268-0100, or toll free (in the U.S.A.) at
1-888 4 VINTEN (1-888-484-6836). You can also fax Vinten at 1-
845-268-
0113. An emergency telephone service is available 24 hours a day, seven days a
week using the 1-
845-268-0100 number (or 1-888-484-6836, toll free in the
U.S.A).
To streamline service and support, the same boards are used in multiple loca-
tions wherever possible. This allows you to swap boards in many cases to isolate
a fault. For example, the 503 Power Amplifier (motor driver) is used twice in
each head and (and six times in each SP-2000 pedestal). The 4 Channel Servo
Board in the head is also used twice in each SP-2000 pedestal. Note however,
that the jumper setting (J1) on the 4 Channel Board must be changed depending
on whether it is used for Steer, Drive or Pan/Tilt.
Safety
Service should only be performed by qualified personnel, who
are familiar with the equipment. At some points inside the
power supplies 120 (or 240) volts AC is exposed, with a danger
of electrical shock. Unless there is a power supply failure, the
highest voltage present in the cable or head should be no more than ±42
VDC. The normal unregulated supply voltages supplied to the head are ±30
VDC.
If you must work on a head that is powered up, place a large
WARNING sign at the controller to alert other personnel that
they should not attempt to use the system.
