Rockwell Automation 440R-MSR17T User Manual
MINOTAUR MSR17T SAFETY RELAYS
ATTENTION: To prevent electrical shocks, disconnect power
source before servicing.
IMPORTANT: Save these instructions for future use.
General
The safety relay by itself can not provide safety. The
safety relay requires proper component application
and
maintenance. The application must anticipate
failures by using system safety risk assessment. This
product must
accordance with the manufacturer’s instructions as
well as applicable standards.
Mounting
The units must be mounted on a 35 mm DIN rail.
Construction
The relay has (4) groups of terminals:
1. Power Terminals:
(+B1 -B2) for 24V DC
2. Input Terminals:
The E-Stop and Gate interlock operator: Ch 1 (S10 &
S11), Ch 2 (S21 & B2) (Fig. 1, 2)
Start button: S10, S33 (Fig. 1, 2)
*3. Safety Output Terminals:
13-14, 23-24
These are monitored outputs. These outputs are
voltage free.
**4. Auxiliary Terminals:
33-34 (K1 Aux.), 43-44 (K2 Aux.)
be installed and maintained in
Applications: E-Stop, Gate Interlock, Expanders
and Auxiliary Relays, Automatic Start
E-Stop (Fig. 1)
a) Use an E-Stop button conforming to EN 418. It must have (2)
Normally Closed (N.C.) contact blocks. The contact blocks
must conform to EN 60947-5-1 positive-opening operation.
b) Use a start/reset momentary pushbutton with (1) Normally
Open (N.O.) contact block.

ATTENTION:
Protection of Safety Circuits.
To avoid contact welding, a fuse (5A quick or 1.6A
*
slow) must be connected externally.
The auxiliary terminals are NOT monitored
**
and must not be used as safety outputs. These
may be used for data and signaling.
Wiring:
Use 0,2-2,5 mm2 (24-14 AWG) Cu only. Typical
screwdriver needed is a flat blade 3 mm (.125 in.) wide
Tighten screws to 0.5-0.8 Nm

Maintenance
The relay and its application must be inspected
periodically based on environmental and
operating conditions. Causes of contamination
must be eliminated. Worn and broken assemblies
must be replaced. Fasteners must be securely
