Replacing the desiccant
Condensation on electronic and optical components
Do not open the photometer if a cold medium is flowing through the lines. Perform this
work procedure only when the system is in a sterilization phase or the medium is at least at
room temperature. Similarly, if the instrument is removed from the line for service work,
make sure that the instrument is at least at room temperature before it is opened.
If the desiccant has to be frequently replaced, the sealing of the instrument should be
checked by a SIGRIST service technician.
The following servicing duty is identical for the PhaseGuard standard version and for
PhaseGuard with integrated field bus interface (Modbus RTU / Profibus DP).
