v 1.4 — September 2015 Altanium Neo2
84 Soft Start Routine
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.
NOTE:Make a note of the zone(s) that are displaying EARTH LEAKAGE and turn the
system’s main breaker off as soon as possible so the problem can be fixed.
Neo2 allows the Earth Leakage check ON or OFF for the entire system to be turned off.
The default setting is ON for all zones. Turning Earth Leakage off is only necessary under
very special circumstances. To turn the Earth Leakage check off please call the nearest
Husky Regional Service and Sales office.
10.3 Soft Start Routine
For many years hot runner molders started their molds by turning on the manifold zones
(larger mass, longer time required to heat up) first. Once the manifolds were hot, they would
turn on the probes (small mass, fast time to heat up) and wait for them to reach setpoint. The
manifold has the potential to grow and shift first and in many cases can misalign itself to the
probes. Also, the material in the manifold channel now has a varied residence heat time to
the material internal to the probes. In each case the possibility of a mold leak or gate
misalignment is added.
With Neo2, all zones warm up simultaneously, rising in temperature at the same rate to
ensure even thermal expansion and identical residence heat time on the material.
During the Soft Start routine Neo2 will display the following:
1. After touching START, Neo2 will begin the Bake Out process if necessary.
The power applied to the heaters varies from the probes to the manifold zones, the
probes receiving less power and the manifolds receiving more. All of the zones increase
in temperature at the same rate to ensure a smooth even thermal transfer within the
mold. This helps to eliminate mold leakage.
2. Once all temperatures are up to their setpoint you are ready to begin molding.
