Over temperature protective device (temperature limiter class 1)
Only CONDITIONER
TM
with lighting unit
The CONDITIONER
TM
with lighting unit is equipped with an internal temperature limiter, class 1 acc. to
DIN 12880. It serves to protect the unit and prevents danger caused by considerable defects.
If a temperature of about 66°C is reached, the temperature limiter (8) permanently switches off the unit,
the red pilot lamp (7) of the temperature limiter in the lateral control panel lights up, the messages “Etc”
and the actual temperature in the inner chamber are displayed alternately on the upper display, and the
controller emits an intermittent alarm sound (8.1.4 on page 37). The alarm sound can be muted by hitting
controller button
.
When the temperature limiter has responded, check the setting of the safety controller, parameter “Al.5”
(chap. 7.1.). The value should be
≤
55°C (Table 3 on page 30).
If the value of parameter “Al.5” is
≤
55°C and nevertheless the temperature limiter class 1
responds, the device is faulty.
Take the unit out of operation and have it checked by your local Datacolor service
representative to find the cause fort he excessive temperature and the failure of the safety
controller (temperature safety device class 3.1).
If the value of parameter “Al.5” is
≥
66°C, the temperature limiter might have been triggered because the
safety controller (temperature safety device class 3.1) has not been set. In this case, you can take the
unit into operation again after checking all operating parameters (Table 3 on page 30).
•
Let cool down the inner chamber temperature below 55°C.
•
Set parameter “Al.5” at the controller to 55°C (chapter 6 on page 29)
•
Unscrew the protecting cap of the temperature limiter (8) in the lateral control panel and press down
the green push-button below.
•
Hit
button to quit he alarm message at the controller.
The red pilot lamp (7) goes off, and the upper controller display displays only the actual inner chamber
temperature.
If the alarm occurs again, please contact your local Datacolor service representative.
7.3
Over temperature protective device (temperature fuse class 1)
Only CONDITIONER
TM
without lighting unit
The sample conditioning cabinet is equipped with an internal temperature fuse, class 1 acc. to DIN
12880. It serves to protect the unit and prevents danger caused by considerable defects.
If the limit temperature 110 °C is exceeded, the temperature fuse melts and switches off the cabinet
permanently. It is not possible to take the cabinet into operation again by the user.
This temperature fuse is located internally and can only be changed by a service specialist.
Contact your local Datacolor service representative.
