INTRODUCTION
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 and transfer or progressive tooling. 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.
ABOUT PTM LOADGARD SERIES
PTM LOADGARD series is one of the most advanced load monitoring systems Helm can offer.
Sophisticated features such as smart sampling, adaptive learning, SPC(Statistical Process Control)
Charts, etc. help monitoring the operation of your machine and protect them from faulty operation.
BENEFIT
• Press Protection – protect press components, including dies, from costly damage
• Parts Quality Control – ensure parts are being made (stamped) as specified
Variations in the mechanical press and the part making process have the costly potential of press
damage, waste of material, and downtime. The PTM LOADGARD uses force monitoring for both
press protection and parts quality control. If an excessive force that could potentially damage the
press machine or a variation in force occurs during the part making process are detected, the PTM
LOADGARD triggers an “alarm” and stops the press. This allows the press operator to correct the
potential problem ahead.
PTM (PEAK TONNAGE MODULE)
• PTM is a single channel strain gage sensor input module to process the signal of the strain
gage to analog output.
• PTM provides Auto-Zero® feature (patented by Helm Instrument Co., Inc.). The Auto-Zero®
feature automatically keeps the zero balance of the load signal between every load cycles to
compensate the tonnage variation affected by any environmental conditions changes such as
temperature.

MAIN FEATURES
OPERATING MODES
PTM LOADGARD Series has three function modes controlled by an operator.
• Setup Mode – Used for system setup, Job setup or new job download.
Capacity alarms are active. Trend Alarms are active if the Trend Alarm in
Setup option is enabled from Server Setup screen. Target value is used
for monitoring the Trend alarm conditions as a reference point.
• Learn Mode – Learns new sample value.
Capacity alarms are active. Trend alarms are active if the Trend Alarm in
Setup option is enabled from Server Setup screen. Target value is used
for monitoring the Trend alarm conditions as a reference point.
• Monitor Mode – Adaptive learning can be active in this mode.
Capacity alarms are active. Trend alarms are active. Sample value is
used for monitoring the Trend alarm conditions as a reference point.
LOOK WINDOW TIME (ms) - Only applicable to none Resolver Model
PTM LOADGARD monitors tonnages between the “critical” time of the press stroke called the look
window. 224 points (tonnage readings) per channel are recorded during the look window time from
the look window start trigger point. These points are displayed as a “wave” or “signature” in the
Signature Analysis screen.
SAMPLING (also referred to as “Learning” or “Trending” cycles)
Samples for pre-determined number of press strokes, defined as sample counts in Alarm Setup
screen.
When the sampling is completed, PTM LOADGARD takes an average peak tonnage and / or
tonnage signature per channel (while sampling), and stores as a Sample peak value and/or Sample
Signature per channel and uses it as a reference point for Trend / Tracking Alarm conditions.
• Sample – Sample is the value learned automatically from Learn mode or Monitor mode by
adaptive learn feature. The Sample value is used to calculate the Trend and Tracking
Alarm condition in Monitor mode.
• Target – When you create a new job, Target values need to be entered manually. These
values can be copied from the Sample values when Leaning process is completed for the
job. The Target can be used during Setup or Learn mode to monitor the Trend Alarm
conditions before new Sample values are available or just can be used as visual reference
for each Job.
ALARMS
In normal operation, the Alarm relay is closed for fail safe. When the tonnage alarm(s) condition
is detected, the system opens the TOP STOP relay
• High/Low Capacity – Normally set at machine capacity. This provides the protection for
the Machine. This alarm is active in all modes.
• High/Low Trend – creates high and low tolerance for peak load based on Target or
Sample tonnage. The tolerance values are the allowable tonnage deviation above and
below Sample or Target tonnage. This provides the means to maintain the quality of the
part making. Trend alarms are available in all modes. There is an option to disable the
Trend alarm during Setup or Learn mode.

PTM LOADGARD Series Operators Manual
7
• High/Low Tacking – creates high and low tolerance bands around the sample tonnage
signature for monitoring the alarm condition through out the stroke. Tracking alarm is only
available in Monitor mode
• Press Curve (only available for Resolver based model) – Since a press may have
different force capacities at different angles, the press manufacture may provide a
“through the stroke press-curve and motion curve” set of data points. This alarm is valid
in both setup and Monitor mode.
OTHER FEATURES
• Signature Analysis – Displays the forming force signature for each channel. You can
zoom, read the tonnage value at angle, overlay multiple channels, view multiple peak
tonnage value in bar graph, and more to help you analyzing the force signature.
• Alarm History – You can view last 500 alarm messages with time stamped.
• Peaks History – You can view a peak tonnage history graph of last 10000 strokes.
• SPC (Statistical Process Control) – You can view statistical charts of peak tonnage
variation from selected peak history. Avail SPC charts are Individual & Moving Range,
*Average & Range, *Median & Range, *Average & Std. Deviation, and Histogram
• Jobs Recipe – You create alarm settings per job base and store to Job Recipe for later
quick download to setup the system.
• Adaptive learning – While the system is in Monitor mode, you can enable an Adaptive
Learning option to continuously learn new sample tonnage while monitoring. This will allow
the system to adapt any small gradual variances of the tonnage through time when requires
• Multi-Level Password Protection – you can restrict certain functions or screens of the
system from being accessed by unauthorized personnel or prevent from unauthorized
changes of the system settings. Different level of passwords gives more secure and
effective protection for the system.
