Castell KSS User manual

The KSS is a heavy-duty solenoid
controlled key driven electrical switch
interlock ideal for the controlled isolation or
switching of low current. This product is used
where a process can send a signal to release
a key, e.g. a robot has to finish a cycle prior to
isolation. Upon removal of the key, the KSS
switch contacts change to isolate the process.
This type of isolator should be used for short
term, off load isolation. The unit is ready for
mounting into an existing panel or for surface
mounting within its own IP65 rated enclosure.
The KSS is manufactured from either brass or
stainless steel.
OPERATION
The Castell KSS Solenoid Controlled Switch is typically used for machine isolation in applications where a machine has to
finish a cycle prior to isolation.
KSS Solenoid Controlled Switch
1Key is trapped while power is on,
solenoid is de-energised.
2An external signal is received and
LED is illuminated. Push the button
to energise the solenoid and
remove the key.
3Solenoid is energised, switch is
locked out and key is free.
While the power is on and a machine
is running, the key is trapped in the
Solenoid Controlled Switch.
To release the key, an external signal
must be received to energise the
solenoid. With the solenoid energised,
the LED will illuminate to confirm
that the key can be removed ensuring
the power is off.
The key can now be removed and
taken to open the door lock and
gain access to the machine area.
The KSS is available with different solenoid voltages as AC: 24, 110 or 240 V or DC: 12, 24, 110, 240 V (see order
information on page 7 for more details).
The KSS comes with 4 or 6 contacts as standard with contacts arrangements as 2NO/2NC, 4NC or 3NO/3NC or 6NC.
The KSS is available as a back of panel mount (BOB) and as a surface mount version with an enclosure (FOB).

USAGE
The KSS solenoid controlled switch is designed to be part of a safety system and is used to isolate the power releasing.
The KSS solenoid controlled switch is not designed for security purposes.
No hazardous substances were used in the manufacture of this product.
INSTALLATION
Back of panel units should be mounted to a flat surface using suitable fasteners (please refer to drawing on page 4-5 for
more details). The lock face should be sealed to the panel for ingress protection.
Cables should be connected to the switch in accordance with the applicable wiring diagrams. Ensure that the unit is
bonded for earth continuity (see drawing on page 6 for more installation details).
IMPORTANT: The interlock should be mounted using anti-tamper fasteners to prevent unauthorised removal.
The KSS range of solenoid controlled switches must be installed by a competent and qualified person who has
read and understood these instructions. Please retain this document in your technical file.
The manufacturer should be consulted when use in a corrosive environment is planned.
MAINTENANCE
Periodic visual checks should be carried out by the site manager / safety ocer.
Do not lubricate lock barrel with oil or grease, use CK dry powder graphite if necessary.
In case of defects being detected please contact your nearest Castell Support Department for further actions.
Please see Contact section for contact details.
The interlock must be inspected every 6 months. Safety check should include ensuring the keys can only
be removed in the correct safety operating conditions and that the switches change state (see page 1).

APPLICATION
A KSS Solenoid Controlled Switch safety component
is typically used as part of an integrated safety
system.
A typical application of KSS solenoid controlled
switch is machine guarding. It is usually used in
combination with an access interlock such as the AI
Access Interlock for part body access or an access
interlock with an exchange key for full body access
control such as AIE.
The KSS breaks the machine safety circuit ensuring
a machine is shut down. Once the machine has
completed the cycle, an external signal is received
by the solenoid, which is indicated by an illuminated
LED. Activating the green button on the KSS will
energise the solenoid and enable the key to be
turned and removed ensuring the power cannot be
switched back on.. The key can then be taken to the
AIE access interlock to enable access to the machine.
The machine cannot be restarted until the door is
closed, the bolt is trapped in the AIE access interlock
and the key is removed and taken to the KSS.
