OPERATING INSTRUCTIONS TREND SERIES
INTRODUCTION
You have just purchased the most advanced load monitoring system available. In addition to this system,
HELM INSTRUMENT CO., INC. manufactures a complete line of load monitoring control systems for use
on metal stamping, forging, compaction and assembly presses; cold forming, cold heading, injection molding
and die cast machines.
Standard or custom transducers and load cells are available for in-die monitoring or transfer or progressive
tooling. Easy to use software systems designed for your specific plantwide SPC programs are also
available.
At HELM, quality is inherent not only in the design of our products but in the attitudes of our employees as
well. We're working together to give you the best. After all, that's what our business is all about - providing
innovative instrumentation to help make your manufacturing process more productive and your operation
more effective.
TREND SYSTEM OPERATION
The HELM TREND LOADGARD control system provides protection for the die, the product and the machine
with minimal operator involvement. The Loadgard takes a sample of the forming force of an ideal part,
stores this level in memory and compares each subsequent force level against the ideal.
In addition to capacity alarms for overload protection, the TREND Loadgard features high and low tolerance
limits, set automatically for each channel based on a pre-established setting.
Digital meters display load, machine speed, alarm settings and capacity alarms. Machine stop is initiated
when an off tolerance part is produced.
THE STRAIN GAIN TRANSDUCER OPERATION
The basic function of the HT-400 Strain Gain is to detect the amount of the deflection imposed on the press
as parts are being formed. All Strain Gain sensors are matched to within 1% and therefore can be replaced
without re-calibration of the machine.
The HT-400 Strain Gain sensors are mounted to strategic high stress areas of the machine frame. Signals
from these sensors are routed to the TREND Loadgard for processing. The HT-400 is capable of measuring
either a tension or compression signal.
