SC22-3 Safety Controller 

 

Instruction Manual

System Installation

WARNING . . . 

Connecting 

Controllers in Series

A safety output from one Controller can be 

connected to a safety input of a second Controller . 

However, the 

second Controller should be the only device to which the 
output from the first Controller is connected.
 If a third device is 
also connected to the same safety output (now used as the safety 
input of the second Controller), then during a power transition 
of the second Controller, the input may be a source of current 
momentarily, causing a false ON (Run) signal at the input of the 
third device . 

Failure to connect multiple Controllers correctly 

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

3.6.3  FSD Interfacing Connections

Final switching devices (FSDs) can take many forms, though 

the most common are forced-guided (mechanically linked) 

relays or Interfacing Modules . The mechanical linkage between 

the contacts allows the device to be monitored by the external 

device monitoring circuit for certain failures .
Dependent on the application, the use of FSDs can facilitate 

controlling voltage and current that differs from the OSSD 

outputs of the Controller . FSDs can also be used to control an 

additional number of hazards by creating multiple safety stop 

circuits .

Safety (Protective) Stop Circuits

A safety stop allows for an orderly cessation of motion or 

hazardous situation for safeguarding purposes, which results 

in a stop of motion and removal of power from the MPCEs 

(assuming this does not create additional hazards) . A safety stop 

circuit typically comprises of a minimum of two normally open 

contacts from forced-guided (mechanically linked) relays, which 

are monitored to detect certain failures such that the loss of the 

safety function does not occur (i .e . external device monitoring) . 

Such a circuit can be described as a “safe switching point .”
Typically, safety stop circuits are a series connection of at least 

two N .O . contacts coming from two separate, positive-guided 

relays, each of them controlled by one separate safety output of 

the Controller . The safety function relies on the use of redundant 

contacts to control a single hazard, so that if one contact fails 

ON, the second contact will arrest the hazard and prevent the 

next cycle from occurring .
Interfacing safety stop circuits must be wired so that the safety 

function can not be suspended, overridden, or defeated, unless 

accomplished in a manner at the same or greater degree of 

safety as the machine’s safety-related control system that 

includes the Controller .

The normally open outputs from an interfacing module (see 

Section 2 .1 for models) are a series connection of redundant 

contacts that form safety stop circuits and can be used in either 

single-channel or dual-channel control methods . (See Figure 

3-12 .)
•  Dual-Channel Control. Dual-channel (or two-channel) control 

has the ability to electrically extend the safe switching point 

beyond the FSD contacts . With proper monitoring (i .e ., EDM), 

this method of interfacing is capable of detecting certain 

failures in the control wiring between the safety stop circuit 

and the MPCEs . These failures include a short-circuit of one 

channel to a secondary source of energy or voltage, or the loss 

of the switching action of one of the FSD outputs . The result 

could lead to the loss of redundancy or a complete loss of 

safety if not detected and corrected .

   The possibility of a wiring failure increases as the physical 

distance between the FSD safety stop circuits and the MPCEs 

increase, as the length or the routing of the interconnecting 

wires increases, or if the FSD safety stop circuits and the 

MPCEs are located in different enclosures . Thus, dual-channel 

control with EDM monitoring should be used in any installation 

where the FSDs are located remotely from the MPCEs .

•  Single-Channel Control. Single-channel (or one-channel) 

control, as mentioned, uses a series connection of FSD 

contacts to form a safe switching point . After this point in the 

machine’s safety-related control system, failures can occur that 

would result in the loss of the safety function (e .g ., a short-

circuit to a secondary source of energy or voltage) .

   Thus, this method of interfacing should only be used in 

installations where FSD safety stop circuits and the MPCEs are 

physically located within the same control panel, adjacent to 

each other, and are directly connected to each other; or where 

the possibility of such a failure can be excluded . If this can not 

be achieved, then two-channel control should be used .

Methods to exclude the possibility of these failures include, but 

are not limited to:
•  Physically separating interconnecting control wires from each 

other and from secondary sources of power .

•  Routing interconnecting control wires in separate conduit, runs, 

or channels .

•  Routing interconnecting control wires with low voltage or 

neutral that can not result in energizing the hazard .

•  Locating all elements (modules, switches, devices under 

control, etc .) within the same control panel, adjacent to each 

other, and directly connected with short wires .

•  Properly installing multi-conductor cabling and multiple wires 

that pass through strain-relief fittings . Over-tightening of a 

strain-relief can cause short circuits at that point .

•  Using positive-opening or direct-drive components installed and 

mounted in a positive mode .
