1.1 OVERVIEW
Fig. 1A
Indication: Steps
In this picture all relevant measured values and status of the valves are represented. Also the active step is indicated.
Setpoint DCS:
This value shows the operation setpoint of the tension pressure received from DCS
Actual Setpoint:
This is the currently effective setpoint, e.g. during the lifting of the rollers (P0x1.8)

1.2 INFORMATION
1.2.1 START CONDITION HYDRAULIC
Fig. 2A In this picture all interlocks for starting the hydraulic unit are represented. If all conditions are green, the PLC-Ready- signal to the control system is sent and the hydraulic unit can be started in automatic mode.

After Logon the screen for local mode can be selected:
Fig. 3A
For the service of the single functions the key switch has to be switched to –Local Control-.
Functions: Lift grinding rollers: Lifting of the rollers Lift pressure frame: Lifting of the pressure frame Stop lifting: Stop of the lifting-process (Pump off) Lowering : Lowering of the rollers or the pressure frame Stop Lowering: Stop lowering the rollers or the pressure frame Tension pressure ON: Build up tension pressure , as long as the push button is held

1.4 PARAMETER
a)
b)
Bild 4A In the following 3 pictures the changeable parameters are represented. For the call of the screen the password is necessary. a) Zero calibration Cyl. 1 to 3: Before the first commissioning or at roller exchange the position measurements must be calibrated. For this purpose the current values of the cylinder positions are read off and entered here. After that one all 3 current measured values must indicate zero.

Reading of the actual values from the screen -Overview:

page 16
The three values read off (from Fig. 1A) must be entered now in the upper three fields (in Fig. 4A) with the signs read off:
Fig. 4A
b) Nitrogen pressure P0: Input of the current nitrogen pressure (in Fig. 4A)
Notice: Through the commissioning engineer or customers the accumulators will be filled normally with 70-80 bar nitrogen. At the filling-equipment a pressure gauge is in order to control the pressure. Subsequently the pressure can be checked also by use of a pressure gauge. The nitrogen pressure indicated at the pressure gauge has to be entered here.

c) Lifting position: Setpoint position for starting the main drive. d) Safety stop maximum position: Maximum position that a cylinder may reach. Only relevant, if unevenly lift (Leakage cylinders etc.) or in Local Mode. If a cylinder reaches this position the pump will switched off . The value must be larger than –Lifting position-. e) Tolerance levelling: The levelling procedure will be stopped if the deviation of all 3 cylinders is less than the tolerance . f) Lifting pressure for starting the level control (Valves 28.1, 28.2 and 28.3) g) Delay for start leveling: Before starting the level-control the bypass (27.1 and 27.2) has to be closed. This delay time is the time between closing the bypass and start of level control.

1.5 FAILURE POSITION MEASUREMENT
Fig. 4C
If a position measurement should be defective, one can bridge these here until the measurement is exchanged.
Failure cylinder 1 - 3:
Selection of the cylinder whose measurement is defective. Through selection of the respective cylinder, the value for the defective measurement is formed from the average of the two functioning measurements. Maximally 1 cylinder can be declared as defective.
Reset: Cancelling of the selection (All cylinder measurements OK)

A measurement was declared as defective, so this is indicated in the start screen and in the overview display permanently:
