ProtEX-MAX PD8-6310-WM Explosion-Proof NTEP Certified Batch Controller Instruction Manual

Setting the Decimal Point (
dEc pt
)
The decimal point may be set with up to five decimal places or with no decimal point at all. The rate, total,
and grand total decimal points are independent.
Press the Up arrow to move the decimal point one place to the left. Press the Right arrow to move the
decimal point one place to the right.
Programming the Batch Controller (
prog
)
It is
very important
to read the following information, before proceeding to program the controller:
•
The controller has been factory calibrated to read input frequency in Hz (pulses/sec). The calibration
equipment is traceable to NIST standards.
•
Use the K-Factor menu to match
the rate/totalizer with a flowmeter’s k-factor (pulse/unit of measure).
•
Use the
Scale
menu to scale process inputs without a signal source. A calibrated signal source is not
needed to scale the controller.
The
Program
menu contains the following menus:
1. Enter K-Factor
2. Scale without a signal source
3. Calibrate with a calibrated signal source
4. Total time base & conversion factor
5. Grand total time base & conversion factor
6. Total reset mode for total & grand total
The process inputs may be calibrated or scaled to any display value within the range of the controller.
Additional parameters, not needed for most applications, are programmed in the
Advanced Features
menu; see Advanced Operation and Programming on page 50.
