Description

The INT-05-024 or INT-05-120 Expansion Safety Relay is intended for use as part of a safety circuit. It provides three additional safe output contacts when used with the INT-03 Safety Monitor Relay or INT-04 Emergency-Stop Safety Relay.

The INT-05 uses positive-guided relays along with feedback contacts to the INT-03 or INT-04 safety relay to prevent machine start-up in the event of a component failure.

Voltage to the INT-05 is switched thru the contacts of the INT-03 or INT-04. If a component failure occurs, the feedback loop to the INT-03 or INT-04 prevents machine restart.

TUV Notes:

• 1. Relay conforms to Pollution Degree II, meets EN1760-1:1998, and must be installed in an IP54-type enclosure.
• 2. The wire insulation of connected devices must be rated for 250VAC. The relay meets basic insulation requirements only.
• 3. Input devices must meet requirements of EN60947-5-1.
• 4. The relay must be connected to a primary disconnect device that meets the requirements of EN60947-3.
• 5. Controller meets IP20.
• 6. Test system before operation and after machine maintenance. Controller does not require maintenance.
• 7. The complete system should be tested weekly. If a fault occurs, contact Sentrol Industrial.
• 8. To be used in conjunction with INT-03 or INT-04.

Installation

• 1. Mount the relay on a 35mm DIN rail or panel. See Dimensions.
• 2. Connect the wiring for the switches and relay. See Wiring Diagrams. (For proper operation, DO NOT jumper terminal 1 to terminal 2. Use a momentary button.) For floor mat applications, connect the two floor mat loops from terminal X1 to X2 and from Y1 to Y2.

Caution! The relay is available in either a 24 VDC, 120 VAC, or 230 VAC model. Make sure correct model is used before applying power.

• 3. Use one of the following methods to energize the relay:
• • For E-stop installations, close all E-stop button contacts and monitored contacts, and then press the START button.
• • For floor mat installations, press the START button without an object on the mat.

Note: The INT-05 must be wired as shown as the unit on its own does not fulfill any safety requirements.
