Maintenance
1. Volume expansion during heating up.
2. Moisture absorption in the thermostatic medi-
um.
1. The viscosity of the heat transfer liquid is too
high. à Change the heat transfer liquid or
raise the setpoint temperature.
2. The pump is blocked. à Contact the LAUDA
Service Constant Temperature Equipment (þ
9.5).
1. No liquid in the system. If this occurs, the level
monitoring has failed. à Check whether the
float in the expansion vessel is blocked by for-
eign bodies. Otherwise, contact LAUDA Ser-
vice Constant Temperature Equipment (þ
9.5).
2. With the option "open load" the device draws
air out of the open load. à Move the return
(suction line) into the heat transfer liquid of the
load.
1. Pump level too high. à Select a lower pump
level (þ 7.9.3).
2. Pressure control setpoint pressure too high. à
Reduce setpoint pressure (þ 7.9.4).
3. Maximum pressure too low. à Increase maxi-
mum pressure (þ 7.9.5).
1. Switch for mains voltage setting [400 V;
3/PE~50 Hz or 440-480 V; 3/PE~60 Hz] in
incorrect position à Switch off unit à Check
whether existing mains voltage and frequency
match [400 V; 3/PE~50 Hz or 440-480 V;
3/PE~60 Hz]; if necessary, set the switch
correctly à Remove the top back panel à At
the back of the unit switch the switch into the
correct position à Fit the rear panel again à
Switch on the unit again.
