Low Voltage Mag Pickup (Isolated): Sensitivity: 40 mVp-p to 8 Vp-p
Minimum Input Frequency: 0.001 Hz – Minimum frequency is dependent on high gate setting.
Maximum Input Frequency: 30,000 Hz (10,000 for Low Voltage Mag Pickup)
Input Impedance: Pulse input: Greater than 300 kΩ @ 1 kHz. Open collector/switch input: 4.7 k Ω pull-up to 5 V.
Accuracy: ±0.03% of calibrated span 1 count
Display Update Rate: Total: 10/sec, Rate: 10/sec to 1/1000 sec
Temperature Drift: Rate display is not affected by changes in temperature.
Multi-Point Linearization: 2 to 32 points
Low-Flow Cutoff: 0-999999 (0 disables cutoff function)
Decimal Point: Up to five decimal places or none: d.ddddd, dd.dddd, ddd.ddd, dddd.dd, ddddd.d, or dddddd.
Calibration: May be calibrated using K-factor, scale using internal calibration, or calibrate by applying an external calibration signal.
K-Factor: Field programmable K-factor converts input pulses to rate in engineering units. May be programmed from 0.00001 to 999,999 pulses/unit.
Calibration Range: Input 1 signal may be set anywhere in the range of the controller; input 2 signal may be set anywhere above setting.
Filter: Programmable contact de-bounce filter, 40 to 999 Hz maximum input frequency allowed with low speed filter.
Time Base: Second, minute, hour, or day
Low Gate: 0.1-99.9 seconds; this function determines how often the incoming pulses are calculated and the rate display is updated.
High Gate: 2.0-999.9 seconds; this function determines how long to wait for pulses before the display goes to zero. This function is used to display slow pulse rates.
Note: The combination of the low and high gate functions makes it possible to have a fast display update for fast pulse rates while displaying slow pulse rates, if needed. For example: If the low gate is set to 1.0 second and the high gate to 999.9 second, with a fast pulse rate the display is updated every second; with a slow pulse rate the controller is capable of waiting up to 999.9 seconds before calculating the rate, making it possible to display a very slow rate down to 1 pulse/999.9 second (0.001 pulse/second).

Batch Controller

Rate Display Indication: 0 to 999999, lead zero blanking. “R” LED illuminates while displaying rate.

Grand Total Rollover: Totalizer rolls over when display exceeds 999,999,999. Relay status reflects the display value.
Grand Total Alarms: Up to seven, user selectable under Setup menu. Any set point can be assigned to grand total and may be programmed anywhere in the range of the controller for grand total alarm indication. 
Note that Relay 1 should always be assigned to batch control (total).
Grand Total Reset: Via front panel button, external contact closure on digital inputs, automatically via user selectable preset value and time delay, or through serial communications.
Grand Total Reset Password: A grand total password may be entered to prevent resetting the grand total from the front panel.

Applications

Single and Multi-Stage Batching

The ProtEX-MAX can be used as a single or multi-stage batch controller. Relays assigned to the total act as batch control relays, with additional relays beyond the first including a preclose value. The preclose deactivates the relay before the batch is finished, to allow slower fill rates and a more accurate batch finish. With expansion module relays, up to eight-stage batching is possible. Each additional stage batching relay has an individually programmable preclose amount.

Single Stage Batch Control

Multi-Stage Batch Control

Manual Multi-Stage Batch Control Operation

System Setup
1. Both valves are closed with an empty barrel in place. The batched total is displayed in the upper display, the preset is selected for the lower display.

Batch Start
2. The START button is pressed, with both valves open. The barrel begins to fill.

Preclose Valve
3. When the batch total reaches a value of 50.00 (Preset [55.00] Preclose [5.00]) the full-flow valve closes. The fill rate of the tank slows as a result.

Completed Batch
4. When the batch total equals the preset amount, the restricted-flow valve closes. The barrel is now full. If some overrun occurs, the next batch will adjust for this offset amount to maintain accuracy.

Change Preset
5. After placing a new, empty barrel, a new preset fill amount may be selected with the Batch key, while the process is stopped.

Begin New Batch
6. Press the START key and a new batch will begin. With both valves open, the process continues.

Pause/Stop
7. At any time, the STOP button may be pressed, once to Pause the process, or twice to cancel the batch, which stops the process.

MeterView® Pro Software

MeterView® Pro software is designed for use with ProVu, ProtEX-MAX, or Helios Series meters and allows users to remotely program, monitor, and datalog using a PC. Remote programming allows for all available meter settings to be programmed through an easy, user-friendly interface. The data acquisition feature allows the user to gather readings from a meter at user-selected intervals and generate charts using common tools like Microsoft® Excel. A linearization setup function is also included. With this utility the user can configure up to 32 linearization points and upload them to the meter. All configuration data can be saved to a file for future use.
This software is accessible via the onboard USB connection on all Helios large display meters, ProVu panel meters, and ProVu-based ProtEX-MAX explosion-proof meters produced since 6 September 2016 (firmware version 4.0 or higher). In order for meters produced prior to 6 September 2016 (firmware version 3.1 or lower) to establish digital communications with a PC, a serial communications adapter is required. For an RS-232 connection, use a PDA1232adapter.
To determine the software version of a meter:

1. Go to the Diagnostics menu () and press Enter button.
2. Press Up arrow button and scroll to Information menu (Info).
3. Press Enter to access the software number (), version (), and serial number () information. Write down the information as it is displayed. Continue pressing Enter until all the information is displayed.
4. The meter returns to Run Mode after displaying all the settings.
