KSSE Multi Key Solenoid Controlled Switch
User Manual - Original Language Version
The KSSE is a solenoid controlled, multi-key electrical switch
for the controlled isolation of low current. This product is used
where the controlled isolation of a machine needs to take place,
i.e. where a robot has to  nish a cycle prior to isolation and
where multiple entry points to the protected area are required.
The solenoid is continuously rated, and its position is electrically
monitored. This type of isolator should be used for short term,
off load isolation. The unit is supplied capable of being mounted
into an existing panel or for surface mounting within its own IP65
rated lockable steel enclosure. The KSSE is manufactured from
either brass or stainless steel making it ideal for use in standard
or harsh corrosive environments.
Operation
E20-FSS-3D-F-C/O4-110A
Castell multi key solenoid controlled switches are typically used for machine isolation in applications where a machine
has to  nish a cycle prior to isolation.
1. While the isolation key is free, the power is on. Personnel keys are trapped.
2. By inserting and turning the isolation key in the KSSE, the contact condition changes switching the power off. Once the
machine has fi nished the cycle, a signal is sent to the KSSE to energise the solenoid and an LED illuminates. The personnel
keys can now be released by pushing the button. These keys can be taken by personnel to unlock the doors in the machine
area.
3. The Isolation Keys stay trapped ensuring power is off until all personnel keys are replaced in the KSSE unit.

1. While all keys are trapped, the switch for the main power supply is closed enabling the power supply.
2. By turning and releasing the keys, the contacts condition changes switching the power off. Once the machine has fi nished
the cycle, a signal is sent to the KSSE to energise the solenoid and an LED illuminates. The Keys can now be released by
pushing the button. These keys should be taken by the personnel to unlock the doors in the machine area.
3. The power is off until all keys are replaced in the KSSE unit and turned, switching the contact condition to open.

Usage
Installation
Maintenance
The KSSE multi key solenoid controlled switch is designed to be part of a safety system and is used to isolate the power
releasing a key which is then used to gain access to a hazardous area via an access interlock such as the AI, AIE or Salus.
The KSSE multi key solenoid controlled switch is not designed for security purposes.
No hazardous substances were used in the manufacture of this product. The product can be disposed of in standard waste.
Back of panel units should be mounted to a at surface using suitable fasteners. Please refer to drawing on page 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 5 for more installation details).
IMPORTANT:
The interlock should be mounted using anti-tamper fasteners to prevent unauthorised removal.
The KSSE range of multi key solenoid controlled switches must be installed by a competent and qualied person who
has read and understood these instructions. Please retain this document in your technical le.
Periodic visual checks should be carried out by the site manager / safety ofcer.
Do not lubricate lock barrel with oil or grease, use CK Dry Powder Graphite if necessary.
In case of defects beeing detected please contact your nearest Castell Support Department for further actions.
Please see Contact section for contact details.

Application
A typical application of KSSE multi key solenoid controleld
switch is machine guarding. It is usually used in combination
with an access interlock such as the Salus for part body
access or an AIE access interlock with an exchange key for
full body access control.
The KSS breaks the machine safety circuit, ensuring a
machine is shut down once the isolation key is inserted
and turned into the unit. 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 KSSE will enable the personnel keys to
be turned and removed ensuring the power is locked out.
The keys can then be taken to the AIE double key access
interlocks to enable access to the machine.
The machine cannot be restarted until all doors are closed,
and all personnel keys returned to the KSSE multi key
solenoid controlled switch.
