Despite its robust construction, the Minilab, Model PVF-C, is a precise
mechanical measurement device and needs appropriate care.
Before performing any maintenance or calibration, ensure that
the power is switched OFF at the Main Switch. Always follow
Lockout and Tagout procedures.
7.1 Daily Maintenance
• Remove and clean any sand/dirt deposits in the working area
with a brush and wipe the operating elements clean with a soft
cloth.
As an added measure of safety and equipment care, ensure
that all doors are closed after maintenance.
The CPU does not have a backup battery. All data is stored in the
Micro Memory Card. The CPU cannot run without it. Removal of this
card will prevent the equipment from operating.
Incorrect operation of the selector switch can result
in CPU content being deleted. In this case, the
program and all Minilab data will be lost; Minilab
operation will be halted until the program can be
reloaded with corresponding Siemens software.
Further literature may be found on the Siemens
website.
7.2 Quarterly Maintenance (Every Three Months)
• Perform the commissioning adjustments as described in
Section 5.1 to ensure proper performance of the testing
equipment.
