SECTION 4
MAINTENANCE
4.1
GENERAL INFORMATION
A high degree of reliability has been achieved in the Model Q2080 through the simplicity of its mechanical
design and the extensive use of microelectronics. The Model Q2080 is designed for fast, easy sub-assembly replace-
ment with no adjustments. This greatly reduces the amount of downtime for unscheduled repairs.
4.2
MAINTENANCE PRECAUTIONS
To avoid damage to the Model Q2080 and personal injury to the service technician, observe the following
precautions during service activity:
1.
Avoid harsh shocks to the drive.
2.
Do NOT open or remove the plastic bubble or its seals unless the drive is in a Class 100 dean environment.
3.
Do not lift the drive by the face plate or the PCBA.
4.
Do not move the drive for 30 seconds after power is removed to insure that the actuator is automatically
locked.
5.
Potentially hazardous AC voltage is present on the underside of the drive for the AC spindle drive motor.
6.
Exercise caution when operating the drive with the cabinet and drive belt shield removed. Stay clear of the
belt motor and spindle pulley.
4.3
PREVENTIVE MAINTENANCE
The Model Q2080 does not require any preventive maintenance.
4.4
MAINTENANCE PROCEDURES
Corrective maintenance on the Model Q2080 requires certain minimum levels of technical expertise and
facilities. Capabilities in this area will vary greatly from user to user. Maintenance procedures for the Model Q2080
are categorized into two levels. The first level involves on-site exchange of sub-assemblies or the drive itself. The
second level involves service center and/or factory repair or refurbishment of assemblies and the printed circuit
board.
4.4.1 LEVEL 1 MAINTENANCE
Level 1 maintenance consists of circuit board exchange, external sub-assembly replacement, drive belt replace-
ment, frequency and voltage conversions, and unit replacement.
Tools
The following tools are required for Levell maintenance procedures:
1. An assortment of hand tools adequate for electronic/mechanical repair
2. 1\vo torque driver handles (preset to 14 and 22 in.-lbs) with a #8 Allen tip, a
#2
Phillips tip, and a 3/32 hex
socket tip.
Spare Parts
The following spare parts should be on hand when performing Levell maintenance procdedures:
1. Drive control PCBA (Quantum Part No. 20-20800)
2.
AC and/or DC drive motor
3. Drive power transistor assembly (Quantum Part No. 79-49075)
REV A (01/84)
