WARNING
!
INTERFACING BOTH OUTPUT SIGNAL SWITCHING DEVICES (OSSD)
Failure to follow these instructions could result in serious injury or death.
•
Unless the same degree of safety is maintained, never wire an intermediate device(s) (PLC, PES, PC) be
-
tween the safety module outputs and the master stop control element it switches such that a failure causes
a loss of the safety stop command or the failure allows the safety function to be suspended, overridden, or
defeated.
•
Connect both OSSD outputs to the machine control so that the machine’s safety-related control system
interrupts the circuit to the machine primary control element(s), resulting in a non-hazardous condition.
WARNING
!
OSSD INTERFACING
Failure to properly interface the OSSD Outputs to the guarded machine could result in serious injury or death.
•
To ensure proper operation, the Banner device output parameters and machine input parameters must be
considered when interfacing the Banner device OSSD outputs to machine inputs. Machine control circuitry
must be designed so that the maximum load resistance value is not exceeded and that the maximum spec
-
ified OSSD Off-state voltage does not result in an On condition.
External device monitoring (EDM) is a function used to monitor the state of the external, positively guided (mechanically linked) machine control
contacts (Final Switching Devives (FSD) and/or MPCEs). The SI-RF Safety Switch does not include the EDM function. As a result, the SI-RF
Safety Switch should be used with an external safety monitoring device that monitors the status of the two SI-RF Safety Switch OSSDs and is
capable of providing the EDM function.
Examples of appropriate external safety monitoring devices include Banner SC10-2roe, SC26-2, and XS26-2 Safety Controllers; Banner
UM-FA-9A and UM-FA-11A Universal Input Safety Modules; and Safety PLCs.
WARNING
!
THE SI-RF SAFETY SWITCH DOES NOT HAVE EXTERNAL DEVICE MONITORING (EDM).
•
If EDM is required for the application, it must be implemented in the external control.
3.8.2.1. Fault-Tolerant Output Feature
Faults that do not immediately compromise the safe operation of the SI-RF Safety Switch (for example safety output to external potential, cross
-
wire short safety output) result in a delayed switch-off of the safety outputs.
The safety outputs switch off when the error warning exceeds 20 minutes. In case of error warning, the red LED flashes code BC2.
Use this fault-tolerant output feature to run down the machinery in a controlled manner. After fixing the fault, the error message is confirmed by
a voltage reset. The safe outputs enable and allow a restart.
3.8.3. Wiring for Single PNP (SI-RFP)
Five-conductor, cannot be wired in series
A movable safety guard is monitored through one SI-RF Safety Switch. The safety outputs of the SI-RF Safety Switch are connected to a safety
monitoring module. When the safety guard is closed (actuator detected), the SI-RF Safety Switch switches on its safety outputs.
When being used individually, the SI-RFP series offers a simple 5-pin wiring scheme. Use the optional PNP auxiliary output to transfer non-safety
related status information.
