13.9 Total breakdown of heater HBr
13.10Temperature outside limit value range
HBr
n.a.
Total breakdown of heater is an alarm message in hot run-
ner controllers. It is output additional with the current alarm,
when a break is detected in the heating circuit, i.e. no heat-
ing current is measured.
How it works
Indicates the user a disconnection in the heating circuit. The
heating current measurement determines a heating current
of 0.0 A.
What good is it
The alarm total breakdown of heater provides the user ad-
ditionally with a specific indication of the error in the hot run-
ner or the wiring, and provides the ability to pinpoint errors
quickly and correct it.

Wiring
Check wiring system
Heating
Check heating, measure electrical resistance
Subnormal tempera-
ture
The actual temperature value is monitored in the hot runner
controller on limits. An actual temperature value outside the
set limits, generates this alarm by changing the color of the
frame of the affected zones.
Excess temperature
How it works
The parameters
[P013]Upper absolute limit value,
[P014]Lower absolute limit value and the parameters
[P011]Upper relative limit value,
limit value define the range of the actual temperature value.
What good is it
Exceeds the actual temperature value the limits, the user
gets a specific indication of the error. He can remove this
without deviation and delay.
Remedy
Reason
Trouble Shooting
Limit value too low
Check settings for limit value and adjust it, if necessary
