Service Philosophy
Servicing is supported at three levels by Vinten Inc. after the 12-month warranty
period expires:
•
On-site service may be contracted from Vinten Inc. or through the
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 or 1-888 4VINTEN numbers.
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 six times in
the SP-2000/X-Y (and twice in each head). The 4 Channel Servo Board is used
twice in the SP-2000/X-Y (and once in each head). 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
WARNING: 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 potential of electrical shock. Unless there is a
power supply failure, the highest voltage present in the cable or pedestal
should be no more than +42 VDC (±42 VDC in older dual voltage systems).
The normal unregulated supply voltages supplied to the head are ±30 VDC.
WARNING: When you are working on a pedestal, disconnect
the Power/Data cable to isolate the pedestal from the system.
