Unit description
The unit is used for safe standstill monitoring. It is designed for use on
` Standstill monitoring on plants with
dangerous machine parts or tools (EN 1088 clause 7.4),
` Safety circuits in accordance with
EN 60204-1 and IEC 60204-1. Standstill is only detected on power­free measuring circuits. Residual volt­ages, induced voltages or drives with­in the position control will prevent safe standstill detection!
Safety features
` Relays K1 and K2 are interlocked in
such a way that the unit cannot be
switched back on in the case of
contact welding or an open circuit.
` The unit monitors the measuring
circuits for open circuit. If an open
circuit occurs between the unit and
the motor or on the motor itself, the
unit immediately switches off.
` The standstill monitor prevents the
plant from being enabled in the fol-
lowing cases
– Power supply failure
– Component failure
– Measuring circuits are open cir-
cuit
– Coil defect/open circuit

Safe monitoring relays
Standstill
PSWZ X1P
Function description
The device uses two separate measur­ing channels to measure the regener­ated voltage, induced from the motor during the rundown period or during start-up. If the voltage falls below the set response value (standstill thresh­old), the standstill monitor enables the monitored plant. If the voltage ex­ceeds the set release value, the stand­still monitor disables the monitored plant. To reactivate, the voltage at both channels must fall below the response value U
within the time tg (simultane-
on
ity monitoring). To do this the feed­back loop Y1-Y2 must be closed. If the

simultaneity requirement is exceeded, the standstill monitor does not enable the monitored plant. The unit can be reactivated by switching 24 VDC on and off at the RESET input. The response value U
can be set
on
jointly for both channels in order to suit the motor that is to be monitored. The release value U
(hysteresis) corre-
off
sponds to twice the response value. When used with frequency converters, the PSWZ X1P cannot detect standstill until the controller inhibit has been switched off. After the supply voltage is switched on, the unit performs a self test. The unit simulates a situation in which the release value is exceeded and the
measuring circuit has an open circuit. The correct function of the output relay and feedback loop is also tested. The test takes ca. 1.5 s. Operating modes:
` Single-channel operation:
– One measuring circuit affects
both channels
– No redundancy (failsafe) in the
measuring circuits
` Dual-channel operation:
– Two redundant (identical) meas-
uring circuits affect channel 1 and 2
– Monitoring of voltages in the
measuring circuit (failsafe in the event of a short circuit)

Terminal configuration
Installation
` The safety relay should be installed
in a control cabinet with a protec­tion type of at least IP54.
` Use the notch on the rear of the unit
to attach it to a DIN rail.
` Ensure the unit is mounted securely
on a vertical DIN rail (35 mm) by us­ing a fixing element (e.g. retaining bracket or an end angle).
