INT Monitor Relay

INT-03-024

INT-03-120

INT-03

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.

Description

The INT-03-024 or INT-03-120 Safety Monitor Relay is intended for use as a part of a

safety circuit in guard interlock applications. It is a safety relay which uses positive-

guided relays, configured for self-checking, to inhibit machine start-up in the event of

an internal component failure.

Both normally-open and normally-closed inputs are required. Multiple N.O. contacts

can be wired in series while multiple N.C. contacts can be wired in parallel. Upon

failure of either the N.O. or N.C. contact, the relay will turn off and prevent restart.

The INT-03 relay can also monitor contacts on external relays for controlling expansion

block relays (Sentrol INT-05 and INT-06).

Installation

Guardswitch

Inputs: Wire the GuardSwitches

™

in series and in parallel as shown in

the wiring diagram. When first applying power to the GuardSwitch

™

Monitor Relay,

with no jumper or button from Terminal 1 to Terminal 2, realy will not energize.

With a jumper installed from Terminal 1 to Terminal 2, relay energizes when all guards

are in place (autostart).

With a RESET button installed from Termainal 1 to Terminal 2, relay energizes after

all guards are in place and RESET button is pressed. The monitor contacts must also

be closed.

Authorized Outputs: The designer must perform a risk analysis and be aware of the

applicable safety standards of their machine. The designer has a choice of how to use

the output contacts. The output contacts can be used in combination with an

Emergency Stop Relay circuit with a “reset” function. (“The restoring of an interlocked

safeguard shall not initiate machine motion or operation where this can result in a

hazardous condition. IEC 204-1.) The reset circuit should not be wired to disconnect

power to the GuardSwitch Monitor Relay, or it will be difficult to distinguish between a

GuardSwitch failure and a normal reset function.

Input Power: The GuardSwitch Monitor Relay is available in either a 24 VDC or 120

VAC model. Make sure the correct model is used before applying power as shown in the

wiring diagram.
