Intended audience This document is intended for authorized personnel. Reading prerequisites It is assumed that the reader of this document has: • Basic knowledge of ABB safety products. • Knowledge of machine safety. • Knowledge of safety devices. Special notes... -
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 12: Connecting To A Screw Compression Type Terminal
Connecting to a screw compression type terminal Use a screwdriver with slot size 3,5 mm. Open the terminal before inserting a wire. 2. Insert the wire in the correct terminal. 3. Close the terminal and secure the wire with torque 0,7 Nm ±0,1. Connecting to a push-in type terminal Press the actuating lever. - Page 13 The maximal wire length is limited by the resistive loading to the maximum wire resistance divided with the wire resistance per length of the unit. The maximal wire length is limited by capacitive loading to (100nF - external capacitive loading) divided with the wire capacitance per length of unit. is resistance for the complete wire.

Page 15: Safety Device Interface
Connectors: Terminals in connection blocks. NO contact: The NO contact is open when the relay is inactivated and closed when the relay is activated. A relay output is in safe state when the contact is open. Caution! The NO contact is open at all types of internal failures and is a safe Note! output. -
Page 16: Manual Reset
Manual reset Always use the manual reset function when a reset button is installed. Warning! When at least one input safety signal is not accepted, the safety relay enters to inactive mode. The MODE LED is blue and at least one of the CH1/CH2 LEDs will turn OFF and the reset button light is static on. -

Page 19: One Channel Connection
One channel connection The safety device contact must be closed before the safety relay can be set in active mode. Opening of the safety device contact inactivates the safe outputs. One channel connection, +24 VDC static signal One channel connection from T1 Two channels connection with equivalent contacts Both contacts must be closed before the safety relay can be set in active mode. -
Page 20: Two Channels Connection With Antivalent Contacts
Two channels connection with equivalent contacts from T1/T2 Two channels connection with antivalent contacts In the example the R1 contact must be closed and the R2 contact must be opened before the safety relay can be set in active mode. Switching one or both of the contacts inactivates the safety relay. -
Page 21: Pressure Sensitive Device Connection
Two channels connection with OSSD external signals Pressure sensitive device connection Both T1/R1 and T2/R2 safety inputs must be used for this function. The total resistance of the circuit including inactivated pressure sensitive devices and cables is shown in chapter. A force activated pressure sensitive device will result in a short-circuit over T1/R1 and T2/R2. -
Page 22: Reset Button Connection Example
Two-hand safety device connection with square wave signal Reset button connection example To use the multi-reset function the X1 inputs must be connected in parallel from the reset button. The X4 outputs must be parallel connected to the reset button indication light. All the safety relays involved in the multi-reset chain must be set to manual reset. -
Page 23: Configuration
Configuration The safety relay starts in configuration mode the first time it is used. Configuration mode is indicated with flashing segments on the display. The safety relay must be configured and power cycled (power off and on) before it is in operation. The safety relay can be configured into preset mode or custom mode. -
Page 24: Display
Display The display is placed in the upper part of the front panel. The display consists of three seven- segment digits. The display is used for navigation in the setting menus. Error codes are also shown on the display. Password A three-digit password will be set when using customized settings. -
