Unit description
Gertebeschreibung
The unit is used for safe standstill
monitoring. It is designed for use on
`Standstill monitoring functions 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 power-
free measuring circuits. Residual volt-
ages, induced voltages or drives with-
in the position control will prevent safe
standstill detection!
Safety features
][Sicherheitseigenschaften Stillstand
`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

Function description
][Funktionen_einkanalig_Stillstand
The device uses two separate measur-
ing channels to measure the regener-
ated voltage, induced from the motor
during the rundown period or during
start-up. If the voltage falls below the
set response value (standstill thresh-
old), the standstill monitor enables the
monitored plant. If the voltage ex-
ceeds the set release value, the stand-
still monitor disables the monitored
plant.
To reactivate, the voltage at both
channels must fall below the response
value Uon within the time tg(simultane-
ity monitoring). To do this the feed-
back 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 Uon can be set
jointly for both channels in order to suit
the motor that is to be monitored. The
release value Uoff (hysteresis) corre-
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.
][Funktionen_zweikanalig_Stillstand
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)

][Verdrahtung_Si_unverz_1Hi_unverz_Stillstand
Please note:
`Information given in the “Technical
details” must be followed.
`Outputs 13-14, 23-24 are safety
contacts, output 41-42 is an auxilia-
ry contact (e.g. for display).
`To prevent contact welding, a fuse
should be connected before the
output contacts (see technical de-
tails).
`Use copper wire that can withstand
60/75 °C.
`When used with converters: Use
screened cable for the wiring be-
tween the standstill monitor and the
motor. Connect the cable screening
on the motor.

Installation
Montage_PNOZ_X
`The safety relay should be installed
in a control cabinet with a protec-
tion 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 us-
ing a fixing element (e.g. retaining
bracket or an end angle).
