  • Page 6: Safety

    Safety Intended use The intended use of the Sentry safety relay is to monitor the state of a safety device and depending on the state, activate or inactivate the outputs within the system response time. The protective function of the safety device is only safe if the safety relay is correctly connected and configured.

  • Page 7: Product Description

    Product description Sentry safety relays Sentry safety relays provide safe stop and start of monitored devices to prevent errors. The following safety device types are applicable for the Sentry safety relays: • 1 channel safety device. • 2 channel safety device with equivalent contacts. •...

  • Page 9: Installation

    Installation Installing precautions Follow the instructions carefully to avoid personal injury or damage to the device. The safety relay shall be attached on a 35 mm DIN rail in a lockable enclosure that has at least protection class IP54. Sentry safety relays shall be installed in an upright position. Make sure there is at least 10 mm distance between the safety relay and other non-Sentry units to prevent uncontrolled heating.

  • Page 10: Removing The Safety Relay From The Din Rail

    Removing the safety relay from the DIN rail Use a screwdriver to unlock the DIN relay latching device from the DIN rail. 2. Pull the bottom rear side of the safety relay away from the DIN rail until a click is heard. 3.

  • Page 11: Connecting Precautions

    Connecting precautions Disconnect the power supply before attaching or removing the Warning! connection blocks. Make sure that connection blocks and wires are clearly marked for correct connections. Use applicable requirements in IEC 60204‑1 for wire connections. Make sure that the wires are fitted with crimp terminals or ferrules before connection, unless solid copper conductors are used.

  • Page 15: Safety Device Interface

    Arc suppression for inductive loads is recommended to get a longer Note! lifetime for the relay contacts. Safety device interface Sentry safety relays have interfaces with inputs/outputs (I/O:s) for connections of safety devices. Inputs/Outputs T1/T2 detect short circuits to +24 VDC or other OSSD signals and are designed for supplying signals to different types of safety devices.
