Operating Instructions: Alfred Solenoid Controlled Guard Lock
16
Electrical Connection
1.
Check that the Alfred Solenoid Controlled Guard Lock product to be installed is of the same electrical type and voltage
rating as the machine control circuits. This information can be found on a label, fixed to the back of the device. Note that
the Ex Rated Solenoid Module is designed to operate at +/-10% of the nominal supply voltage. The use of an incorrect
voltage can seriously damage the device.
2.
Remove the Lid Assembly from the Ex Rated Solenoid Module of the Alfred Solenoid Controlled Guard Lock product
following the guidelines and instructions detailed in the Lid Assembly Requirements section above.
3.
Make sure the electrical supply is fully isolated before any connection is made.
4.
Attach suitable Cable and Cable Gland – See requirements above for further detail.
5.
Bond the Device enclosure to Earth via the Internal Earthing point provided (see Figure 11) and also, if required, the
additional External Earthing point (see Figure 11). See Earthing requirements above for further detail.
6.
Connect all required internal wiring to the Safety Circuits and Gate Monitor Circuits. See Wiring Diagrams below and
function descriptions below for further detail.
The electrical system must incorporate fuse protection for all circuits, using a Quick-Acting (F) fuse (maximum rating 3A, 250v
to IEC 127). All fuses must be inserted on the positive line.
Terminals 2 & 14.
(Safety Circuit I)
These Contacts should be connected in series with the external device which isolates all electrical parts of the machine that
are being protected by the Alfred Solenoid Controlled Guard Lock product.
Each safety circuit should be connected to an appropriate evaluation device e.g. a ‘safety relay’. The diagnostic coverage
of the evaluations device will affect the safety performance of the system. Connecting safety circuits of multiple products in
series may reduce the performance level of the system according to DIN EN 13849-1 owing to reduced fault recognition.
Terminals 3 & 4.
(Solenoid operating supply).
By applying the solenoid control supply to these terminals, the machine control can operate the locking mechanism in the
Solenoid Module.
Terminals 5 & 7.
(Safety Circuit II)
This is a second, isolated Safety Circuit for redundancy (see the description above).
Terminal 6.
Input voltage to terminal 12 for Gate Monitor Circuit and terminal 13 Solenoid Monitor Circuit.
Terminal 12.
(Guard Open Output Signal).
Control signal produced by the Ex Rated Solenoid Module to indicate that the Machine Guarding is in an open state or that
the primary Key has been removed depending on the complete Alfred Product type and application. This signal can be used
for indication and / or machine control.
Terminal 13.
(Guard Unlocked Output Signal).
Control signal produced by the Ex Rated Solenoid Module to indicate that the Module is unlocked and ready to open. This
signal can be used for indication and / or machine control.
Terminals 6 & 12.
(Guard Open Output Signal / Gate Monitor).
Control signal produced by the Alfred Safety Switch to indicate that the Machine Guarding is in an open state or that the
primary Key has been operated depending on the complete Alfred Product type and application. This signal can be used for
indication and / or machine control.
7.
Once all wiring is complete, refit the Lid Assembly to the Ex Rated Solenoid Module Enclosure following the guidelines and
instructions detailed in the Lid Assembly Requirements section above.
8.
Fully test and operate the complete Alfred Solenoid Controlled Guard Lock product for correct electrical and mechanical
operation.
