7.1
Maintenance
The TP 28 1300 E itself is maintenance-free and cannot be repaired by the user. In case of a
defect, the device must be returned to the manufacturer for repair.
CAUTION! Material damage!
When opening the device, critical parts or components can be damaged.
Never open the device and perform any repair yourself.
For safe operation of the calibrator, the following checks must be carried out at regular in-
tervals:
Before use:
Check the calibrator for damage.
Annually:
Subject all the parts of the calibrator to a visual inspection for corrosion, wear and dam-
age.
Have a trained technical person carry out a safety inspection of all the electrical parts in
accordance with BGV A2.
Recalibration:
Send the calibrator for Recalibration (
§ 7.3) once annually or after a maximum of 500
operating hours to SIKA.
Thermal fuse:
The thermal fuses of the calibrator are located on the underside and are integrated in the
mains connection. If there is a mains voltage present, but the display is dark and the fan is
not running, you should check the fuses and replace them if required.
Pull the mains cable from the calibrator.
Prise open the fuse compartment from the bottom with a fingernail or a flat screwdriver.
Remove the compartment with the fuses.
Check the fuses and replace the faulty fuses.
IMPORTANT! Only use fuses of the same type (T 10 AH 250 V).
Always replace both fuses, even if only one is defective.
Fit the fuse compartment back in place and connect the mains connecting cable (
§ 4.2
"Electrical connection").
Should the fuses blow repeatedly, there is probably a fault in the calibrator.
In this case, send the calibrator to SIKA for repairs (
§ 6+§ 6.1).
