Dual-channel guard door monitoring circuit with interlocking device to ISO 14119
• At least one contact with positive break required.
• Wire breakage and earth leakage in the control circuits are
detected.
• Cross-wire shorts between the monitoring circuits are not
detected.
• Control category 4 – PL e to DIN EN ISO 13849-1 possible
(with protective wiring)
Dual-channel guard door monitoring circuit with interlocking device to ISO 14119
• At least one contact with positive break required.
• Wire breakage and earth leakage in the control circuits are
detected.
• Cross-wire shorts between the guard monitoring circuits are
detected.
• Control category 4 – PL e to DIN EN ISO 13849-1 possible
Dual-channel control of a safety-related electronic (micro processor-based) safety guard with p-type
transistor outputs e.g. AOPD's to EN IEC 61496
• Wire breakage and earth leakage in the control circuits are
detected.
• The safety-monitoring module therefore is not equipped with a
cross-wire short detection here. The safety-monitoring module
therefore is not equipped with a cross-wire short detection here.
• If cross-wire shorts in the control circuits are detected by the
safety guard:
Control category 4 – PL "e" to DIN EN ISO 13 849-1 possible.
Dual-channel control of magnetic safety switches according to EN 60947-5-3
• Wire breakage and earth leakage in the control circuits are
detected.
• Cross-wire shorts between the control circuits are not detected.
• Control category 3 – PL e to DIN EN ISO 13849-1 possible
