ELECTRICAL CONNECTION
All EM85XX balancing machines operate on single-phase power and are supplied preset for
the specified power supply (115 V, 280V or 230 V AC). To modify this setting, the
transformer primary must be adjusted to the available mains voltage.
SERVICE PROGRAMS
The purpose of these programs is to provide the information required for quickly and
efficiently testing the various parts of the machine.
The selection procedure is as follows:
•
press either of the two arrow keys, and then, within two seconds, the wheel size setting
key. This selects the first service program (number 87).
•
press the arrow keys to select the next (or previous) available program, until you have
selected the program you wish to use. Each selection results in display of the code
8X...9X (X varies with the program) on the LH display and a flashing "Ent" on the RH
display to indicate the need to confirm the selection by pressing "Enter";
•
press the "Enter" key to confirm.
If the presetting is not confirmed within about three seconds, the system automatically exits
the Utility environment.
The various selectable programs (each with a different X) are described below.
87 Working environments:
allows three different operators to work at the same time;
Selecting the program results in the machine displaying:
-
message 1, 2 or 3 on the RH display;
-
message OP (operator) on the LH display.
This service program allows selection of the operator (1, 2 or 3)
by pressing "Enter".
To confirm selection of another operator, press F.
For each working environment, the following data are stored:
-
balancing mode;
-
wheel size;
-
the last step in the optimization procedure (OPT).
To exit from the program (and the service environment) press F.
88 Sensitivity calibration (2 spins):
Allows calibration of the sensitivity.
This must be done when the user considers that the calibration is outside the tolerance range,
or when the machine itself prompts the procedure by displaying "Err CAL".
When the program is selected the machine displays “ d F ”, hence:
-
fit the calibration disc on the balancing machine;
-
place the inside sensor touching the calibration disc in line with the hole with the blue outline.
-
press F to confirm, and then move the inside sensor to the rest position.
-
the displays will show "CAL --I".
-
fit the calibration weight to the outside of the disc (position 1);
-
run a first spin;
-
at the end of the spin the displays will show "CAL --I";
-
fit the calibration weight to the outside of the disc again, but this time at 180° to the
previous position (position 2);
-
run a second spin;
