When one of the safety switches connected in series enters a non-detection state, the indicators of all other safety switches flash in green to notify the operator.

When a door is intentionally kept open, the indicator of the safety switch on that door changes to red and the indicators of the safety switches on all other doors flash in green.
The operator can recognize immediately the equipment status and which door is open.

The visible type actuator allows the light from the switch body to pass through so that the indicator light is visible from the actuator side. |
The SG-P series standard units, which are used as master units, can output safety signals all at once (OSSD1 / OSSD2).
The sub units used as slave units minimize the wiring for a cascade connection.
There is no need to purchase a dedicated controller. The presently used safety controller / circuit can be connected directly. Up to 30 units can be connected, thus contributing to wire-saving.
* High-code models (SG-P20□-M-□, SG-P20□-S) only
During the initial setting, bring the switch body close to the actuator and turn on the power to let the safety switch detect the actuator for 3 seconds. This simple procedure completes the pairing. In a cascade connection, pairing can be achieved all at once by simply turning on the power. This reduces the man-hours required for starting up the equipment.
* Low-code models (SG-P10□-M-□, SG-P10□-S) do not require pairing.
The ISO 14119:2013* international standard stipulates a design requirement that deactivations of safety functions shall be minimized.
Export of equipment sometimes requires to meet this standard. The SG-P series products are available with two different coding levels: High-code models and Low-code models. The High-code models are compatible with ISO 14119* coding level (high level coded actuators) and prevent intentional deactivation of their safety function.

Renewal of maintenance procedures by eliminating the use of potentially dangerous deactivation tool (dummy or spare key)Desired maintenance mode can be easy constructed by mounting
the coded actuator to the switch body. |
Mounting the maintenance actuator to the
SG-P unit enables the control output function for the maintenance mode.
The following two types of maintenance actuators are available:
Overall maintenance type (SG-PK-M1)
Individual maintenance type (SG-PK-M2)
■ One-touch installation
* Individual maintenance type actuator (SG-PK-M2) is mounted on a compact type unit in the above example. |
Indicating the name of the department that owns the maintenance actuator and the name of person in charge on a commercially available key tag and attaching it to each unit makes it easy to manage the users. |

* | Be sure to evaluate the control output correctly. |
---|---|
* | Can be used only with the standard switch body. |
* | All switch bodies in series connection change to the maintenance mode. |
* | The indicators on the switch bodies in series connection change in color. |
* | All doors with the switch bodies in series connection can be opened and closed. Take care not to allow unauthorized persons to open or close the doors. |
|
* | Be sure to evaluate the control output correctly. |
---|---|
* | Can be used with the standard or sub switch body. |
* | Can be installed to multiple switch bodies for simultaneous use. |
* | Only the switch bodies installed with this product type can be individually changed to the maintenance mode. |
* | The indicators on the switch bodies in series connection change in color. |
When the SG-P unit is mounted with the maintenance actuator, the large indicator lights in "yellow".
The workers can readily recognize that the equipment is in maintenance.
