Edwards INT-03 Series Installation Instructions

Series INT 03 Monitor Installation Sheet outputs The designer must perform a risk analysis and aware of the applicable safety standards of their machine The has a choice of how to use the output contacts output contacts can be used in combination with an Emergency Relay circuit with a function restoring of an safeguard shall not initiate machine motion or operation this can result in a hazardous condition IEC 204 1 reset circuit should not be wired to disconnect power to the Monitor Relay or it will be difficult to distinguish between GuardSwitch failure and a normal reset function power The GuardSwitch Monitor Relay is available in either a VDC or 120 VAC model Make sure the correct model is used applying power as shown in the wiring diagram 1 Dimensions INT 03 024 or INT 03 120 Safety Monitor Relay is intended for as a part of a safety circuit in guard interlock applications It is a relay which uses positive guided relays configured for self to inhibit machine start up in the event of an internal failure normally open and normally closed inputs are required Multiple contacts can be wired in series while multiple NC contacts can be in parallel Upon failure of either the NO or NC contact the relay turn off and prevent restart The INT 03 relay can also monitor on external relays for controlling expansion block relays INT 05 and INT 06 Relay conforms to Pollution Degree II meets EN1760 1 1998 and be installed in an IP54 type enclosure The wire insulation of connected devices must be rated for VAC The relay meets basic insulation requirements only devices must meet requirements of EN60947 5 1 The relay must be connected to a primary disconnect device that the requirements of EN60947 3 System total response time must not exceed 200 ms Controller meets IP20 and must be connected to safety category 4 or sensing device Test system before operation and after machine maintenance does not require maintenance The complete system should be tested weekly If a fault occurs Sentrol Industrial inputs Wire the GuardSwitches in series and in parallel shown in the wiring diagram When first applying power to the Monitor Relay with no jumper or button from Terminal 1 Terminal 2 the relay will not energize a jumper installed from Terminal 1 to Terminal 2 the relay when all guards are in place autostart a RESET button installed from Terminal 1 to Terminal 2 the relay after all guards are in place and the RESET button is The monitor contacts must also be closed 2 Typical wiring diagram 1030522 REV E ISS 09SEP15 4 3 Wiring for multiple switches GuardSwitches are shown with the actuators in position guard is One 300 BT Series GuardSwitch is required for each gate Up to 50 switches can be used with INT 03 When the BLT switch models the voltage drop 30 must be into consideration Only outputs AB and CD are safety outputs Auxiliary form C E F G may fail in an unsafe condition and should only be for signaling The circuit wiring in Figure 3 can be as follows WHT White wire be WHT or YLW yellow BLU Blue wire can be BLU or GRN 4 Wiring for category 4 GuardSwitches are shown with the actuators in position guard is Inputs are shown with safety guard in closed position Two Series Guardswitch and one INT relay are required for each gate Only outputs AB and CD are safety outputs Auxiliary form C E F G may fail in an unsafe condition and should only be for signaling The circuit wiring in Figure 4 can be as follows WHT White wire be WHT or YLW yellow BLU Blue wire can be BLU or GRN 4 1030522 REV E ISS 09SEP15 information file number E57361 all models information contact information see www edwardsfiresafety com 2015 Walter Kidde Portable Equipment Inc rights reserved contacts or closed G G VDC 100 m A 250 V 5 20 mm F T VAC 10 5 VA 50 60 Hz mA 250 V 5 20 mm F T oz oz gauge max to 149 to 65 to 95 noncondensing specifications wiring size range humidity supply or L1 L2 fuse fuse inputs X1 X2 Y1 Y2 terminals circuit voltage circuit current resistance outputs A B C D terminals time signaling outputs E F G terminals Transient protection is required across the load when switching inductive load VAC 60 VDC A resistive each output 100 ms A 250 V 5 20 mm VDC mA max ms typical VAC 30 VDC A resistive specifications number input L1 L2 VDC VAC 10 50 60 Hz 5 VA fuse required acting 1 4 A 250 V 5 x 20 mm F T acting 80 mA 250 V 5 x 20 mm F T 1030522 REV E ISS 09SEP15 4 4 1030522 REV E ISS 09SEP15
