IKA C-MAG HS7, Manual

Page: 53 / 220

Error codes 53
Err. 13 – Hotplate safety sensor, open-circuit
Causes
› target / current different of the adjustable safety circuit
for minimum temperature monitoring
Effect › heating switched off
Solutions
› after switching on, change the SAFE TEMP to a different
value; if this solves the issue, the previous value can be
reset by switching the device off and on again
Err. 14 – External temperature sensor, short-circuit
Causes
› short circuit in temperature sensor plug
› short circuit in the cable or temperature sensor
Effect › heating switched off
Solutions
› check the plug
› replace the temperature sensor
Err. 21 – Fault during heating plate safety test
Causes › safety relay does not open
Effect › heating switched off
Solutions › switch device off, leave to cool and switch on again
Err. 22 – Fault during heating plate safety test
Causes › S_CHECK cannot generate H_S_TEMP
Effect › heating switched off
Solutions › switch device off, leave to cool and switch on again
Err. 24 – Heating plate temperature
is higher than the set safety temperature
Causes
› SAFE TEMP H (Hotplate) has been set to lower than the
current temperature of the heating plate
› disconnection of heating plate control temperature sensor
Effect › heating switched off
Solutions
› leave the heating plate to cool
› set the SAFE TEMP H (Hotplate) higher
