Tools and Fixings Required
Pin Hex Driver Bit (Provided)
1/4” Driver (to suit above)
Ø8.2mm Drill or M5 Drill and Tap
3.5mm Flat Blade Electrical Screwdriver
4 x M8 screws for rear-xing. (Screws must be suitable length for a minimum of 10mm thread engagement with Stop
module. Required screw type and class; A2 70. Required torque setting; 4-6 Nm.)
4 x M5 Cap-Head screws for through-xing. (Screws must be suitable length for a minimum of 6mm thread engagement if
mounting to a threaded panel. Required screw type and class; A2 70. Required torque setting; 2-4 Nm.)
Required Torque Settings:
If removed during mounting, re-orientation or electrical wiring, all supplied xing screws of the complete Guard Interlocking
Device must be retted using the following torque settings;
- M3 Screws – 0.8-1.0 Nm.
- M4 Screws – 2-4 Nm.
- M5 Screws – 2-4 Nm.
- M8 Screws (required for device mounting but not supplied) – 4-6 Nm.
If M4 Lid screws have been removed during electrical wiring and installation, they must be fully retted to a torque setting of
2-4 Nm to guarantee IP protection level.
Mounting
1. Mount the safety switch only in the correctly assembled condition.
2. Locate the safety switch so that inspection and replacement are possible.
3. Using the driver bit provided, loosen the 4 tamperproof lid screws. Remove the lid assembly complete with the
retained screws.
4. Remove the Tongue assembly from the complete Guard Interlocking Device by pulling it out of the head. Mount the safety
unit only in the correctly assembled condition.
5. M o u n t t h e e n c l o s u r e a s s e m b l y t o g e t h e r w i t h h e a d a s s e m b l y t o a  a t m e t a l , s t a t i c p a r t o f t h e m a c h i n e . U s e M 5 s c r e w s

8. The installation and operation of the complete Guard Interlocking Device must take into account the requirements of
EN ISO 14119; in particular Section 7 – Design for minimising defeat possibilities.
9. The complete Guard Interlocking Device must not be used as a mechanical stop. Where applicable, precautions must be
made to ensure the door or gate of any guarded area has su󰀩cient support and stops to prevent the impact on the
Guard Interlocking Device.
10. If tted in conjunction with an S40 Push IR Escape Release module, the complete Guard Interlocking\Device must be
mounted in the correctly assembled condition so that the Escape Release action is only possible from within the
guarded area (danger zone).
Operating Instructions: Stop - Non Solenoid Switch Body

Electrical Connection
1. Check that the complete Guard Interlocking Device 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, xed to the device. Note that all device
are designed to operate at +/-10% of the nominal supply voltage. The use of an incorrect voltage can seriously
damage the device. AC devices are suitable for 50/60 Hz.
2. Make sure the electrical supply is isolated and attach suitable conduit(s) via M20 cable gland(s). Correct size cable
glands/blanking plugs must be used to achieve IP67 & IP69K sealing.
3. Bond the enclosure to Earth potential via the Earth point provided. The earth wire used must be multi-stranded Yellow
and Green PVC sheathed and approved to BS 6231 with conductor cross-sectional area of 2.5mm².
4. Make the electrical connections using 28 - 24 AWG cable referring to the information below.

rating 3A, 250v to IEC 127).
Terminal 4. (Supply common return).
For DC installations, connect this terminal to 0v of the machine control system.
For AC installations, this will be Neutral.
Terminals 1 & 5. (Safety Circuit I)
These Contacts should be connected in series with the device which isolates all electrical parts of the machine that are being
protected by the S40Stop. Each safety circuit should be connected to an appropriate evaluation device e.g. a ‘safety relay’.
The diagnostic coverage of the evaluations device will a󰀨ect the safety performance of the system. Connecting safety circuits
of multiple guard devices in series may reduce the performance level of the system according to DIN EN 13849-1 owing to
reduced fault recognition.
Terminals 3 & 7. (Safety Circuit II)
This is a second, isolated Safety Circuit (See above).
Terminal 2. (Permanent Supply)
Permanent supply voltage to guard interlocking device.
Terminal 6. (Guard Open Output Signal).
Control signal produced by the guard interlocking device to indicate that the guard is in an open state. This signal can be
used for indication and/or machine control.
5. When all wiring is complete, replace the lid. Test the unit for correct operation.
Switch Ratings: 230V Max 50/60Hz, AC15, 3A/DC12, 3A
Warning: This device does not contain the Machine Reset or Restart facility after an escape or auxiliary release of
the guard locking. Addition measures are required to achieve the reset of the machine system.
Electrical Function Test
Close the guard and start the machine. Open the guard. The machine must stop! The machine must not start when the
guard is open!

Service and Inspection
Regular inspection of the following is necessary to ensure trouble-free, lasting operation:
• Correct operating function
• Secure mounting of components
• Debris and wear
• Sealing of cable entry
• Loose cable terminals or plug connectors
There are no user serviceable parts in the S40Stop. If damage or wear is found with an assembly, please contact your local
Fortress stockist for a replacement. The complete safety switch must be replaced after 1 million switching operations.
Disposal
The S40 Stop unit does not contain any certied hazardous materials so should be disposed of as industrial waste.
Liability Coverage is Voided Under the Following Conditions:
• If these instructions are not followed
• Non-compliance with safety regulations
• Installation and electrical connection not performed by authorised personnel
• Non-implementation of functional checks.
Protection Against Environmental Inuences
A lasting and correct safety function requires that the unit be protected against the ingress of foreign bodies such as swarf,
sand, blasting shot, etc. The unit is to be mounted away from the machine, or by the use of anti-vibration mountings, in order
to avoid the e󰀨ects of vibration, shock and bump.
Use in Dusty Environments: Careful product selection is required, which is best performed under the guidance of a Fortress
Sales Representative, in order to assess the dust type and product style required.
Use in Corrosive Environments: Careful product selection is required, which is best performed under the guidance of a
Fortress Sales Representative.
The manufacturer reserves the right to modify the design at any time and without notice.
This guide should be retained for future reference.
