Maintenance And Cleaning; Accessories - IKA C-MAG HS 7 control Instructions Manual

Maintenance and cleaning

› The device is maintenance-free� It is only subject to the natural wear and tear of components
and their statistical failure rate�
/// Cleaning:
› For cleaning disconnect the mains plug!
› Use only cleaning agents which have been approved by IKA to clean IKA devices�
These are: water (containing surfactant) and isopropyl alcohol�
› Wear protective gloves during cleaning the devices�
› Electrical devices may not be placed in the cleansing agent for the purpose of cleaning�
› Do not allow moisture to get into the device when cleaning�
› Before using another than the recommended method for cleaning or decontamination, the
user must ascertain with IKA that this method does not destroy the device�
/// Spare parts order:
› When ordering spare parts, please give:
- device type�
- serial number, see type plate�
- position number and description of spare part, see www.ika.com�
- software version�
/// Repair:
› Please only send devices in for repair that have been cleaned and are free of materials which
might present health hazards�
› For repair, please request the "Safety Declaration (Decontamination Certificate)" from
IKA or use the download printout of it from IKA website at www.ika.com�
› If your appliance requires repair, return it in its original packaging� Storage packaging is not
sufficient when sending the device - also use appropriate transport packaging�

Error codes
› The fault is shown by an error code on the display as following if the error occurs�
Proceed as follows in such cases:
- Turn off the device by using the main switch (left « on, right « off)�
- Carry out corrective measures�
- Restart the device�
Error code | Causes | Effect | Solutions
Er02 - Watchdog error
Causes › PC does not transmit any data within the set watchdog time
› connection to PC interrupted
Effect › heating switched off
› motor switched off
Solutions › change watchdog time
› transmit data from PC within set watchdog time (OUT_WDx@m)
› check cable and plug
Er03 - Temperature inside device is higher than 80 °C
Causes › heat accumulation between heating plate and housing
› permitted ambient temperature exceeded
Effect › heating switched off
Solutions › switch device off, leave to cool and switch on again
› change experiment
› observe maximum permissible ambient temperature
Er04 - Motor control is unavailable
Causes › motor blocked or overloaded
Effect › heating switched off
› motor switched off
Solutions › reduce load torque or use smaller magnetic rods
› reduce target speed
Er05 - No temperature increase measured by temperature sensor
(selected time in menu)
Causes › sensor not in medium
› volume of medium to be measured too large
› heat conductivity of medium to be measured too low
› heat conductivity of the vessel is too low
› in the case of indirect heating, the overall heat conductivity resistance is too
large
Effect › heating switched off
Solutions › place the sensor in the medium
› reduce the volume of the media
› use a carrier fluid with better heat conductivity properties
› replace the glass vessel with a metal pot
› increase the "Time-out" period
