User Manual - Original Language Version
Operation
S20-FSB-F-CC4-110A
1. While the power is on and a machine is running, the key is trapped in the Solenoid Controlled Switch.
2. To release the key, an external signal must be received to energise the solenoid. With the solenoid energised,
the LED will illuminate to conrm that the key can be removed ensuring the power is off.
3. The key can now be removed and taken to open the door lock and gain access to the machine area.
The KSS is available for different switching loads as KSS20 and KSS32 (20 amps power isolation respectively. See order infor-
mation on page 7 for more details).
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).

KSS Solenoid Controlled Switch
Key is trapped while power is on,
solenoid is de-energised.
An external signal is received
and LED is illuminated. Push the
button to energise the solenoid
and remove the key.
Solenoid is energised, switch is
locked out and key is free.
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 nish 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 lockable steel enclosure. The KSS
is manufactured from either brass or stainless steel making it
suitable for use in standard or harsh corrosive environments.
The Castell KSS Solenoid Controlled Switch is typically used for machine isolation in applications where a machine has to n-
ish a cycle prior to isolation.
