FAQ – Questions and answers about U-TECH PRESS
You need at least the ANM antenna module, the ALM control unit, and the ETM self-test module.
The antenna module (ANM) is located on the machine above the conveyor belt and defines the required hazardous area through an electromagnetic field.
The control unit (ALM) monitors all incoming signals and triggers automatic shutdown of the machine upon entering the hazardous area or in case of a malfunction, such as a UHF receiver failure.
The self-test module (ETM) is mounted on the system and constantly monitors the stability of the electromagnetic field and the flawless operation of the system.
The size of the electromagnetic field for shutting down the system is adjustable via the potentiometer on the ALM. We recommend setting the size as small as possible to avoid potential disturbances next to the conveyor belt. However, depending on the installation location and conditions, field sizes of 4 to 6 meters can be achieved if necessary.
A 24V direct current (DC) connection must be available, ensuring a constant voltage. It may be necessary to install a 24V power supply. The two connected modules, ANM and ETM, do not require a separate power supply.
NOTE: All old systems with serial numbers less than 1454 (GSG202) have a 230V connection. If you are adding a new control unit, make sure to switch to 24V!
Yes. The system includes two separate evaluation logics and two safety relays accordingly.
The Mobile Stop is simply mounted in front of the ANM antenna. Employees equipped with the PSM can now trigger an emergency stop of the system by pressing the red button on the PSM, from a distance of up to 100 meters. This is useful, for example, when an employee identifies a potential hazard at the machine and wants to shut it down as quickly as possible. The system can only be restarted using the same PSM by pressing the green button.
The Authorization Module operates separately from the personnel protection system. With its assistance, one can ensure that only an employee with a functional PSM can activate the system.
Yes, because it is part of the system certification. With its help, employees can ensure before the start of a shift that all PSMs are operational and have enough battery power for at least one shift.
First, we recommend a complete reconfiguration of the system according to the user manual. If this does not resolve the issue, we offer consultation to determine whether the Clearfield 3D or Clearfield 2S products are necessary in this case. An explanation of the modules can be found in the following FAQs.
In pathways that run closely to the ANM antenna mounted above the conveyor belt, unintended triggering of the machine can occur due to the electromagnetic expansion of the field. The Clearfield Module 2S provides the option to prevent this through neutralization fields.
It can occur that electrically powered vehicles, such as electric forklifts, generate an electromagnetic field in the variable kHz range, activating the driver’s Personnel Protection Module (PSM) and generating a return signal that puts the U-Tech PRESS System in emergency stop mode. To prevent this, the Clearfield Module 3D is installed near the driver in the vehicle cabin. It creates a three-dimensional electromagnetic field within the vehicle, deactivating the Personnel Protection Module.
The standard cable lengths between the antenna module and the control unit, as well as between the self-test module and the control unit, are 15m. These can be extended up to a maximum of 30m.
Yes, up to 5 systems can be installed next to each other. It is important to ensure that the respective protection fields do not overlap. To prevent triggering one system from shutting down all systems, it is necessary for each system to be set to a different code (A, B, C, D, E). The control unit ALM and its associated antenna ANM of a system must have the same code (A, B, C, D, E).
