Danger!There is a danger of being drawn into the machine at the intake side of the roll gap. The rotating rolls can draw parts of the body into the machine and are capable of crushing whole limbs. Never reach inside the roll gap and maintain a safe distance from the intake zone.Note!There are two different modes for the roll gap control. In the upper half of this operating screen, you find the data fields for the position control mode and in the lower half there are the data fields for the pressure control mode.• The actual operating mode is indicated by a green «-sign left to the actual values.1) Position control (upper half of the operating screen)Position setpoints SET [mm]• The position setpoints are entered in mm with a precision of three decimal places.• To confirm your entry, you have to press the ENTER button.Danger!Closing the roll can lead to serious crushing.Ensure that no one is standing between the rolls before you close them.• To move the roll to the desired set position, you have to press the concerned „Close“-button (see fig. 4-2).Actual position values ACT [mm]The actual position values are of the same precision. The actual values are displayed distinguished between the left (OP) and the right(NOP) side of the calender.Position correction values CORR.[mm]Besides this there are data entry fields to enter position correction values for the left (OP) and the right side (NOP) of the roll gaps. With this correction you fit the displayed value to the real measured value.Danger!There is a danger of being drawn in to the machine at the intake side of the roll gap. Always measure the roll gap from the delivery side! This is the side of the roll gap, on which both rolls turn outwards (away from the rollgap).• Measure the roll gap against the turning direction of the roll with a feeler gauge on the left (OP) and right (NOP) side.• Calculate the difference of the displayed values and the measured values.• Enter the signed difference as correction to the assigned correction data entry field.• To confirm your entry, you have to press the ENTER button.
