Pilz PSS Series, PSS1 PS 24 V Manual

Overview

The PS Power Supply provides the internal voltage required to operate the module rack, and the 12 V DC required to program the user memory. The unit supply is 24 V DC. A built-in battery is used as a buffer for all the memory components in the standard section. This battery is monitored by the CPU.

There is a switch to turn the supply voltage on and off, making it easier to install the systems in the Series PSS 3100. The supply must be switched off when changing cards.

The module PSS1 PS 24 V is designed for use on the Series PSS 3100 Module Rack.

Installation

Electrostatic discharge can damage the components on the module. Ensure against discharge before touching the module, e.g. by touching an earthed, conductive surface or by wearing an earthed armband.

The PS 24 module should be installed in the first slot of the module rack, as described in the "Series PSS 3000/PSS 3100 Installation Guidelines".
Connect up the supply: 24 V DC as described on the front of the power supply.

Safe electrical isolation must be ensured for the external 24 V supply. Failure to do so could result in electric shock. Power supplies must conform to DIN VDE 0551 / EN 60 742 and DIN VDE 0160.

Turn the "Power" switch to "ON".

When correctly installed, the "POWER" LED will illuminate.

INFORMATION
There must be a break of at least 5 s between switching off the supply voltage and switching on again.

Please ensure:

Copper wiring is used that can withstand a temperature of 75°C.
Torque setting on the screw terminals should be to 0.5... 0.6 Nm.

Pin Assignment

The power supply has a 3-pin plug-in screw connector for connecting the supply voltage.
Pin Assignment

Battery

If the battery voltage drops below 2.5 V, the CPU will issue the error message "S-04". Change the battery at the front of the power supply.

Always switch off the voltage before changing the battery. The CPU will retain data via a capacitor for approx. 2 minutes. If it takes longer than this to change the battery, data will be lost.
