The level of the safety circuit integrity must be determined by risk assessment; this level is dependent on the

configuration, proper installation of external circuitry, and the type and installation of the devices under control (FSDs and

MPCEs). The solid-state safety outputs are suitable for Category 4 PL e / SIL 3 applications when controlled in pairs (not

split) and for applications up to Category 3 PL d / SIL 2 when acting independently (split) when appropriate fault exclusion

has been employed. See 

Figure 67 

on page 88 for hookup examples.

WARNING: Safety Output Lead Resistance

To ensure proper operation, the resistance in the safety output wires should not exceed 10

ohms. A resistance higher than 10 ohms may mask a short between the dual-channel safety outputs

and create an unsafe condition that may lead to serious bodily injury or death.

Common Wire Installation

Consider the wire resistance of the 0 V common wire and the currents flowing in that wire to avoid nuisance lockouts.

Notice the location of the resistance symbol in the diagram below representing 0 V common wire resistance (RL).

Methods to prevent this situation include:

•

Using larger gauge or shorter wires to reduce the resistance (R

L

) of the 0 V common wire

•

Separate the 0 V common wire from the loads connected to the safety controller and the 0 V common wire from

other equipment powered by the common 24 V supply

NOTE: When the Safety Output turns Off, the voltage at that output terminal must drop below 1.7 V

with respect to the 0V terminal on that module. If the voltage is higher than 1.7 V, the Controller will

decide that the output is still on resulting in a lockout. Consider using larger gauge wires, shorter wires,

or using a single point grounding scheme similar to what is shown in the following diagrams.
