DI Safety Relay
(Cat. No. 440R-D22R2)
The DI safety relay in
monitors two devices having mechanical
contacts and is set for monitored manual reset. With the two devices closed,
the operator presses the reset button to energize contactors K1 and K2. The DI
safety relay verifies that contactors K1 and K2 are off by monitoring the
mechanically linked normally closed contacts in the reset circuit. When the DI
safety relay is off, the auxiliary signal at terminal Y32 turns on and reports the
status to a PLC.
Figure 44 - With Two Devices with Mechanical Contacts and Monitored Manual Reset
, a DI safety relay monitors a safety mat and noncontact
interlock with OSSD outputs. Make note of the specific wiring for the mat.
Also, during configuration and for each power-up, the mat must be clear and
the interlock closed. The DI safety relay must be configured for AND logic for
the two inputs. The DI safety relay logic setting is 6: (IN1 AND IN2) OR L12 with
automatic reset. The DI safety relay verifies that contactors K1 and K2 are off
by monitoring the mechanically linked normally closed contacts in the S34
circuit. When the DI safety relay is off, the auxiliary signal at terminal Y32
turns on and reports the status to a PLC. Per ISO 13856-1, safety mat
applications require a manual reset function. For fault detection purposes, all
GSR safety relays used for safety mat control must be configured for
monitored manual reset.
