96 Earth Leakage/Wet Heater Bake Out System
9.2 Earth Leakage/Wet Heater Bake Out System
Altanium is equipped with an advanced Earth Leakage/Wet Heater Bake Out system. From
the moment the system is started, Altanium will constantly check for earth leakage
conditions on every heater in the mold simultaneously. When necessary, it will initiate a low
voltage bake out on the faulty zone(s) to try to bake the moisture out of the heater(s).
9.2.1 Earth Leakage Limit
For X Cards (ICC
2
):
• The system will declare an earth leakage error based on a user settable percentage limit,
or if a zone has not gone through diagnostics, based on a default value of 0.2 amps.
• The system will declare a bake out error based on a user settable Bake Out Limit with a
default value of 0.2 amps and an adjustable range from 0 to 5 amps. Any value of 0.2
amps or higher, but lower than the earth leakage limit, will trigger a bake out error.
• The calculated earth leakage limit or the default value is compared against the
minimum limit and the lower of the two values is applied.
For H Cards (ICC
3
):
• The cards include a sensor specifically for monitoring leakage current in the heater
circuit on a continuous basis. The system will declare an earth leakage error based on a
user settable Earth Leakage Fault Limit with a default value of 500 milliamps and an
adjustable range from 1 to 999 milliamps.
• The system will declare a bake out error based on a user settable Bake Out Limit with a
default value of 200 milliamps and an adjustable range from 1 to 999 milliamps. Any
value of 200 milliamps or higher, but lower than the earth leakage limit, will trigger a
bake out error.
9.2.1.1 Setting the Earth Leakage Percentage Limit
To set the earth leakage percentage limit, do the following:
1. On the System Setup screen, in the Earth Leakage section, touch the Earth Leakage
Limit field.
2. Enter the desired value.
3. Touch the Accept button.
9.2.2 Configuring the Length and Number of Bake Out Cycles
The low voltage bake out process will run up to five cycles, if necessary. The duration of each
cycle can be set from one to 30 minutes. The system mode and system timer indicate the
progress of each bake out cycle.
Once a bake out cycle is complete, the system diagnoses whether another bake out cycle is
required. If the bake out alert enable parameter is turned on and, after the selected number
of bake out cycles have finished, there is enough moisture in the system to warrant another
