Chain of safety features
The device is equipped with a chain of safety features, including a timer switch, a
safety-time-out feature, BREAKSAFE and a temperature limiter.
d
The internal timer switch (K2/K4) is set ex-works to 20 minutes. After 20 minutes, the device
switches off automatically.
The time set on the K4 timer switch must not exceed 20 minutes.
The maximum tanning time of 20 minutes must not be exceeded.
This time must not be extended by the operator under any circumstance, but it can be reduced if
desired (see Section 9.2.).
If a coin-operated timer is attached to the device, it must always match the time set on the
device-integrated timer switch (K2/K4) (see Section 9.2.3).
d
The safety-timing circuit consists of a timing element (K3), which provides the safety-time-out
feature, i.e. after this time period, the device always switches off automatically. The time period
for the safety-time-out feature is set to 110% of the time on the timer switch, i.e. the ex-works
setting is 22 minutes.
d
The BREAKSAFE safety device switches the device off if a transparent filter disk is broken. The
device can be switched on again only after the faulty transparent filter disk has been replaced.
d
The temperature limiter provides temperature monitoring, protecting the tanning unit from excess
temperatures.
The temperature-monitoring feature also limits the temperature of the attachment surface to a safe
value.
Once the device has cooled down sufficiently, it switches on again automatically.
