Page 3: Overview
• In manual mode, maintenance of the RESTART contact closed is not interpreted as AUTO mode. For safe use of the SR ONE M module, it is essential to read and understand the contents of this handbook. Failure to comply with the prescriptions indicated in this handbook may result in very high risks for the operating personnel of the machine protected. -
Page 4: Automatic Mode
SAFETY RELAY MODULE SR ONE M AUTOMATIC MODE In this operating mode, the outputs of the safety module follow the status of the light curtain: • with the protected area free (outputs of the light curtain active), the relay outputs of the unit are active. -
Page 5: Manual Mode
SAFETY RELAY MODULE SR ONE M MANUAL MODE In this operating mode, the outputs of the safety relay are activated only if the protected area is free and after sending the RESTART signal to the module using a push-button or by means of a specific command on the RESTART input (terminal 15). -
Page 6: Connection Of External Contactors K1 And K2
SAFETY RELAY MODULE SR ONE M CONNECTION OF EXTERNAL CONTACTORS K1 AND K2 Control of external contactors K1 K2 can be activated in both operating modes. If this control must be used, the series of normally closed contacts of the external contactors must be connected to terminal 20 of the safety relay (figures 3 and 4). - Page 7 SAFETY RELAY MODULE SR ONE M Figure 4 - Manual operation with K1 K2 relays 8541410 - 19/09/2022 Rev.1...

Page 9: Muting Function
SAFETY RELAY MODULE SR ONE M MUTING FUNCTION The Muting function is a temporary suspension of the safety light curtain’s protective function. Carefully check your risk analysis to assess whether the Muting function is compatible with your application and what additional measures must be taken. - Page 10 SAFETY RELAY MODULE SR ONE M ➔ The MUTING ENABLE command will only enable the muting function and should be generated at the appropriate time by the machine control system (e.g., When the muting function is needed); it has no effect on the deactivation of the muting function. If not used, fix the terminal 11 at +24VDC.

Page 11: Muting Override Function
SAFETY RELAY MODULE SR ONE M MUTING OVERRIDE FUNCTION The OVERRIDE function must be used when the machine stops due to incorrect Muting activation sequences with the material obstructing the guarded opening. In this situation, the module outputs are not active as the light curtain and/or at least one Muting sensor is occupied. -
Page 12: Override With Pulse Control
SAFETY RELAY MODULE SR ONE M OVERRIDE WITH PULSE CONTROL This function is activated inverting (maximum delay = 400ms) the condition of pin 7 and 8 of the receiver using for example a push button (switch). During the override, the 7 and 8 are not controlled. -
