PNOZ e1vp

Operating modes

} Single-channel operation: Input wiring in accordance with EN 60204, no redundancy in
the input circuit; earth faults in the input circuit and start circuit are detected.
} Dual-channel operation: Redundant input circuit; earth faults in the input circuit and
start circuit are detected, with or without detection of shorts between the pushbutton
contacts.
}
Automatic start: Unit is active once the input circuit has been closed.
}
Monitored start: Unit is not active until the start button has been operated and then re-
leased.
}
The start-up test prevents automatic restarting after a power failure and subsequent re-
turn of voltage. The unit checks whether the input circuit is opened and then closed
when supply voltage is applied.
}
Increase in the number of available contacts by connecting contact expander modules
or external contactors/relays.

Selecting sensors

When selecting sensors, you must comply with the technical details of the input circuits on
the PNOZelog units.
Please note:
}
Sensors with mechanical contacts can be used in operating modes with or without de-
tection of shorts across contacts, provided you comply with the technical details
provided by the manufacturer. It is not always possible to use sensors with semicon-
ductor outputs when operating with detection of shorts across contacts.
}
Sensors with pulsed semiconductor outputs are only permitted if the PNOZelog is oper-
ated without detection of shorts across contacts.

Installation

}
The unit 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 (35 mm).
}
When installed vertically: Secure the unit by using a fixing element (e.g. retaining
bracket or end angle).

CAUTION!
Electrostatic discharge can damage components on the safety system!
Ensure against discharge before touching the safety system, e.g. by touch-
ing an earthed, conductive surface or by wearing an earthed armband.
NOTICE
If you are connecting several units logically, please note the guidelines in
the section entitled Logic connection between several units [ 16].
