7 . CALIBRATION OF CONTROL EQUIPMENT
7.1 INTRODUCTION
All the control equipment is factory calibrated before the machine is shipped. Control equipment and safety
devices should nonetheless be checked after a reasonable period of operation. Calibration values are given in
Tables 2 and 3.
All service operations on the control equipment must be carried out by
QUALIFIED PERSONNEL ONLY; incorrect calibration values can cause
serious damage to the unit and personal injury.
