Quick Guide

Instruction Manual

Eight preset logics, safety-certified and compatible up to control category 4 PLe, can be selected by simply turning the rotary switch. The logic customized by user can be stored in the logic No. 0. The OFF delay time can be easily set by simply turning the rotary switch to any one of patterns. The OFF delay time applies to control output 2. In case of setting the OFF delay time to control output 1, the "Configurator SF-C" software is needed.

Use our "Configurator SF-C" software to build your own safety circuits of connected devices, control logic, output modes, etc. No programming skills required! All possible logic combinations created with the "Configurator SF-C" software are already safety-certified by the certification bodies. The software also has a "simulation mode" to test if the prepared logic and safety circuit operates as intended. If the logic is not complete, the software will block its transfer to the SF-C21 unit.

Please make sure that the combination of logics and input devices complies with each machine safety standard.

When any connected input becomes OFF, the entire control output will be OFF. When the muting input becomes ON, the light curtain will be temporarily disabled. Only when the muting input becomes ON following a predefined sequence, the light curtain will be temporarily disabled. When the emergency stop input is OFF, the entire control output will be OFF. When any other input is OFF, its corresponding control output will be OFF.

When the emergency stop input or the input from the back-end process becomes OFF, the entire control output will be OFF. When the input from the front-end process becomes OFF, only its corresponding control output will be OFF. This control is applied when a two-hand operation switch is used for control.Only when both switches of the two-hand operation switch are operated within 0.5 sec., control output will be ON.

Even when the guard (input A) is OFF, if the enabling switch is ON the control output will be ON. If either the emergency switch or input B becomes OFF, the entire control output will be OFF regardless of the status of the input A and emergency switch. Only when mode selection using the key selector is followed by the enabling switch being turned ON, the control output will be ON regardless of the open / close status of the guard. Note that if the emergency stop switch is OFF, the entire control output will be OFF.
