Only authorized personnel should install these devices. Any of the
shown mounting positions and approach directions may be used.
Install the SI-RF Safety Switch so that the display is visible. The
triangular symbols serve for the alignment and should point to each
other.
Immediately replace any damaged SI-RF Safety Switch or actuator
components. They can be replaced separately, with the exception of
the Unique (U) coded version. If you are using the Unique (U) coded
version, the SI-RF Safety Switch and actuator must always be replaced
together.
3.5 Resetting the Inputs
The reset function forces a local confirmation that the safety outputs are switched on after closing the movable safety
guard.
If the moveable guard is opened using a sensor with a reset function, close and open the reset button within 0.25 seconds
(minimum) to 1 second (maximum), after the guard has been closed.
The reset function only applies to the sensor with the reset functionality. This reset feature allows for a local reset at a given
guard but does not allow for an entire safety system reset. If a chain of sensors is cascaded (see
on p. 13), the reset function only applies to SI-RF 3. If SI-RF 1 or 2 are opened then closed, the outputs will switch on
after the guard is closed, without actuating the reset button.
CAUTION: When power is switched on, the safety outputs switch on without actuating the reset button
when the guard is in the closed position.
WARNING:
• Use of Auto or Manual Restart
• Failure to follow these instructions could result in serious injury or death.
• Application of power to the Banner device, the closing of the movable safety guard, or the reset
of a manual restart condition MUST NOT initiate dangerous machine motion. Design the machine
control circuitry so that one or more initiation devices must be engaged (in a conscious act) to
start the machine - in addition to the Banner device going into Run mode.
3.6 Auxiliary Output/Information
The PNP output models (SI-RFS and SI-RFP) have a diagnostic PNP output. The PNP Diagnostic is not safety related.
The PNP Diagnostic output indicates whether the right actuator has been detected (for example, the door is closed).
• Output high (conducting) - Actuator not detected
• Output low (open or non-conducting) - Actuator detected
When the SI-RFS sensors are cascaded, the output only signifies the actuator status of its sensor, not the others in the
string. With manual reset models (SI-RFSL), the auxiliary output changes back to the low state when the actuator is sensed
(does not wait for the reset).
The ISD models (SI-RFD) do not have an auxiliary output.
3.7 In-Series Diagnostic Information
The information transmitted via the In-Series Diagnostic (ISD) interface is not safety related. The diagnostic technology
allows a wide range of sensor information to be loaded into the machine control system.
To interpret the information, Banner diagnostic modules are available. By means of diagnostics, the following information
can be transmitted, among others:
