STR 0PA 23
- after the calibration procedure is finished, the EA is prepared for its operation and starts to
response to control inputs
- if changes to some parameters would be necessary, proceed please according to the
instructions given in the separate attachment No. 74 1053 02.
3.5 Putting an EA into operation when it is necessary to do a change to the stroke (setting
new end positions), and the other parameter setting done by the producer suits to your
needs
When an EA is delivered from the producer without armature, and the setting of other parameters
done by the producer suit to your needs, and it is necessary to do a change to the EA stroke, proceed
as follows:
- connect the EA with the armature to be controlled (according to chapter 2) and fit this assembly
into the specified technology complex,
- connect the EA electrically according to the wiring diagram and chapter Electrical connection... ,
- turn on the power supply, without connection of the control signals fed into ES (input control
signal - ES reports error/warning No.2 - no binary input),
- set the ES (using manual control*) to end position closed and push button C for at least 2s,
until LED ERROR (red), LED MENU (green) and LED PAR (red) come on – the closed end
position is thus recorded in memory – see description in separate annex No. 74 1053 02,
- release the C setting button,
- set the ES (using manual control*) to end position opened and push button O for at least 2s,
until LED ERROR (red), LED MENU (green) and LED PAR (red) come on – the opened end
position is thus recorded in memory – see description in separate annex No. 74 1053 02,
- release the O setting button,
- introduce the EA into an half position (see Note 2 presented above),
- by pressing the P pushbutton on the control unit for at least 2s activate the EA calibration until
LED ERROR (red), LED MENU (green) and LED PAR (red) come on – see also description of
the procedure in separate annex No. 74 1053 02,
- release the adjustment pushbutton P - upon release of the P pushbutton, the calibration process
is started,
- turn on the control signals, EA is ready for operation and responds to control inputs,
- if any of the parameters need to be changed, proceed according to the instructions in separate
annex No. 74 1053 02,
* This This applies to setting of EA to be controlled by 2P and 3P or 3P/2P switched by I2, at the same time
with standard setting of menu 9 FAILURE REACTION: STOP!
If the input control signal is set to one of the ranges starting from 0 mA, it is necessary to change the range to a
different one. If this is not the case and a control signal is not supplied, the servodrive output component will
take up the position corresponding to 0 mA. After recording the new limit positions change the value of the input
control signal and response to error to the required parameters.
Note: in cases where the sequence is implemented using a PC in the EHL Explorer programme or using local
control, neither the change of response to error nor disconnection of the control signals is required.
3.6 Setting other parameters
If changes to some parameters would be necessary, proceed please according to the instructions
given in the separate attachment No 74 1053 02.
3.7 Gear unit adjustment
Switching-off thrusts for the „Opening“ direction (S1 power switch) and for the „Closing“ direction
(power switch S2) as well are set by the producer to a certain value with a ±10% tolerance. These
values are given in the specification table No.1.
It isn’t possible to set and change the gear unit to different thrust values without using
a test equipment for measuring the thrust. When overloaded, EA switches off in any position of the
stroke beyond the set range of the blocking of the switching-off from thrust in the stroke end positions.
The blocking of the switching-off from thrust can be chosen for a certain range of the stroke starting
from the stroke end position, for a period from 0 up to 20 s (see setting the MENU 3 in the separate
attachment No. 74 1053 02).
