Card Location:
Uses one slot (any location) PLCs
PLC Communication:
Through input and output registers; allocate 12 input and 12 output registers for Modicon 984 Compact;6 IN, 6 OUT for TSX Quantum.
Operating Temperature:
32 to 130 °F (0 to 55 °C)
Tonnage Sensors:
AVG Autotech's SAC-M1030-SEN strain gage sensor provides 4-20 mA signal for tonnage. (Existing strain gages may be used with AVG Autotech's SAC-M1030-SENA amplifier.)
Number of Sensors:
M7450-PT2N—2 sensors, M7450-PT4N—4 sensors
Counters:
Two-Total Number of Hits and Number of Good Parts
Position Transducer:Resolver. AVG Autotech's Series RL100 or E7R
Resolver Cable:
CBL-10T22-xxxx, 22 AWG, 5 twisted pairs, overall foil shielded cable.
Resolver Cable Length:
2,500 ft (762 m) max. shielded twisted-pair.
PROGRAMMABLE LIMITS:
Six limits for each installed sensor. The Limit comparisons can be selectively disabled, except for Positive Tonnage Press Limit.
Positive Tonnage Press Limit:
Programmed in Tons for Press Overload Protection-cannot be disabled.
Negative Tonnage Press Limit:
For Snap through or Reverse tonnage protection—can be disabled.
Die Protect Band:
Defined by Die Protect High and Low Limits. Both limits programmed as deviation from Reference Tons, either in Tons or in Percent of Reference Ton Value (choice is programmable)—comparison can be disabled.
Process Trend Band:
Defined by Process High and Low Limits. Both limits programmed as deviation from Process Base Tons, either in tons or in percent of the Base Tons-comparison can be disabled. (Process Base Tonnage is the running average of tonnage measured over the last several cycles; number of cycles for averaging is programmable.)

Offset Limits:
The sensor signal in the idle state should be around 4 mA. If the sensor signal wanders outside offset limits, and Offset Fault will be generated indicating that for some reason (broken wire, mechanical damage, etc.) the offset reading has been changed and needs to be corrected. High Offset Limit restricts the maxi-mum Positive Press Protect Limit. Low Offset Limit restricts the maxi-mum Negative Press Protect Limit. Also, when either Offset Limit setting is violated (signal outside the limits) both the Under Die/Process Output and Over Die/Process Output will deenergize.
CONTROL INPUTS:
Program Enable:
Input must be TRUE to change any value.
Press Cycle Input:
A FALSE-to-TRUE transition signifies end of a press cycle. Input should occur ±10° of TDC.
OUTPUTS:
Four transistor outputs—all outputs are fail safe.
Positive Tonnage Press Limit—
Output deenergizes if Measured Tonnage exceeds Positive Tonnage Press Limit.
Negative Tonnage Press Limit—
Output deenergizes if Measured Tonnage exceeds Negative Tonnage Press Limit.
Over Die/Process Limit—
Output deenergizes if Measured Tonnage is greater than Die and/or Process High Limit.
Under Die/Process Limit—
Output deenergizes if Measured Tonnage is less than Die and/or Process Low Limit.
