6.5 Monitoring the system vacuum and defining limit values
The ejector has integrated sensors for measuring the vacuum.
The current vacuum level is shown on the display.
The limit values are set in the main menu using the parameters [
5P1
], [
rP1
], [
5P2
] and [
rP2
].
Limit values SP1 and rP1 are used by the control function to control the vacuum.
Overview of the limit values:
Limit value parameter
Description
SP1
Switching point for air-saving regulation
rP1
Reset point for air-saving regulation
SP2
Activation value of “Part Present” signal output
rP2
Deactivation value of “Part Present” signal output
6.6 Calibrating the sensor
Since the sensor integrated in the ejector is subject to variation due to the manufacturing process, we rec-
ommend calibrating the sensor after installation. In order to calibrate the ejector, the system’s pneumatic
circuits must be open to the atmosphere.
A zero offset is only possible in the range of ±3 percent of the end value of the measuring range.
If the permissible limit of ±3% is exceeded, error code [
E03
] will appear on the display.
The zero-point adjustment function is executed in the main menu using the parameter [
CAL
].
1. To adjust the zero point, press the
button several times until [
CAL
] appears on the display.
2. Confirm using the
button.
