Integrity Series

Description

The INT-04 Series Emergency-Stop (E-Stop) Safety Relays are designed for use as part
of a safety circuit in emergency-stop or safety floor mat sensing applications. Each is
a safety relay that uses positive-guided relays, configured for self-checking, to inhibit
machine restart in case of internal component failure.

The INT-04 relay can also monitor contacts on external relays for controlling primary
machine control elements or expansion block relays (INT-05 or INT-06).

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. System total response time must not exceed 200ms.

6. Controller meets IP20 and must be connected to safety category 4 mat or
sensing device.

7. Test system before operation and after machine maintenance. Controller does not
require maintenance.

8. The complete system should be tested weekly. If a fault occurs, contact
Sentrol Industrial.

Installation

1. Mount the relay on a 35mm DIN rail or panel. See

2. Connect the wiring for the switches and relay. See
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 you are using the correct model before you apply 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: Use only outputs A, B, C, and D for safety outputs. The auxiliary outputs E, F,

and G may fail in an unsafe condition and should only be used for signaling.

E-Stop Relay

When installed as an E-stop relay, the device monitors both contacts on the E-stop
buttons to ensure both have opened and closed to allow machine restart. Multiple
contacts can be wired in series. Upon failure of either contact, the relay turns off and
prevents a restart.

Safety Floor Mat Relay

When installed as a Safety Floor Mat relay, the INT-04 monitors both loops of a safety
floor mat. The safety outputs of the INT-04 turn off when an operator steps on the mat.
The relay incorporates loop break detection to turn off if one of the loops breaks or
becomes disconnected.
