4.3.1 CS AM-01••••-TC00
This version is intended for use in applications in which asymmetries of the motor
phases occur while at a standstill. This may be the case, e.g., if the motor is controlled
by an inverter that only produces the brake voltages in one phase.
4.3.2 CS AM-01••••-TA00
This version is intended for use in applications in which the asymmetries of the motor
phases occur during movement. This may be the case, e.g., if the motor is controlled
by an inverter that produces asymmetric voltages in the different phases during ac-
celerations and braking.
4.3.3 CS AM-01••••-TD0
This version corresponds to version CS AM-01••••-TC00, but is designed for shorter
cycle times and, thus, for completely automated processes.
4.3.4 CS AM-01••••-UR1
This version is intended for use in applications with high noise level in which a low
sensitivity of the input channels is not critical.

Notes:
In case of star/delta starting, connect the module to the ends of a single winding.
For direct current motors connect + with L1 and - with L3.
4.5 Increase of number and load capacity of contacts
If necessary the number and the load capacity of output contacts can be increased
by using external contactors with forcibly guided contacts. Connect the feedback con-
tacts of the contactors to the feedback circuit Y1-Y2.

7 INSTRUCTIONS FOR PROPER USE
7.1 Installation
Attention: Do not exceed the tightening torque of the terminal screws specified
in the present operating instructions.
Attention: Observe the wiring of the terminals: incorrect wiring can damage the
RES
device which may result in loss of the safety function.
- The device was developed for use with one- or three-phase AC motors.
- The module can also be used with motors with inverter control: in this case, the
reset in case compatibility of the two electronic devices must be checked in advance. The connection
of fault
between module and inverter must be performed using a shielded cable with which
the shield is attached to the motor. The module detects machine standstill exclusively
by measuring the residual voltages in the phases while the motor is at a standstill.
Possible disturbances, induced voltages or residual voltages for the drive, which are
produced by electronic inverters, affect the correct detection of the motor standstill.
- The module can, in principle, be used with DC motors, but proper polarity must be
ensured (positive pole on L1, negative pole on L3).
- The device may only be installed and used if these technical requirements and all
safety standards relevant to use have been evaluated and implemented.
- Install only inside a cabinet with protection degree not less than IP54 according to
EN 60529.
- Always affix the device with the specific DIN rail adaptor acc. to EN 60715.
- Do not stress the device with bending and torsion.
- Do not modify or open the device for any reason.
- The device carries out an operator protection function. Any inadequate installation
or tampering can cause serious injuries and even death, property damage, and eco-
nomic losses.
- These devices must not be bypassed, removed or disabled in any other way.
- If the machine where the device is installed is used for a purpose other than that
specified, the device may not provide the operator with efficient protection.
- The safety category of the system (according to EN ISO 13849-1), including the
safety device, also depends on the external components connected to it and their
type.
- Before installation, make sure the device is not damaged in any part.
- Before commissioning, check the correct functioning of the module according to the
instructions of the operating diagrams (see paragraph OPERATION).
31
- Avoid excessive bending of connection cables in order to prevent any short circuits
or power failures.
- Do not paint or varnish the device.
- Do not drill the device.
- Do not use the device as a support or rest for other structures, such as raceways,
sliding guides or similar.
- Before commissioning, make sure that the entire machine (or system) complies with
all applicable standards and EMC directive requirements.
- The documentation required for correct installation and maintenance is available
online in various languages on the Pizzato Elettrica website.
- Should the installer be unable to fully understand the documents, the product must
not be installed and the necessary assistance may be requested from the manufac-
32
turer (see paragraph SUPPORT).
- Always attach the following instructions to the manual of the machine in which the
device is installed.
- These operating instructions must be kept available for consultation at any time and
for the whole period of use of the device.
7.2 Do not use in the following environments
- In environments where continual changes in temperature cause the formation of
condensation inside the device.
- In environments where the application causes the device to be subjected to strong
impacts or vibrations.
- In environments with the presence of explosive or flammable gases or dusts.
- In environments containing strongly aggressive chemicals, where the products used
coming into contact with the device may impair its physical or functional integrity.
- Prior to installation, the installer must always ensure that the device is suitable for
use under the ambient conditions on site.
