PD8-6310 ProtEX- MAX Explosion-Proof Pulse Input Batch Controller
The ProtEX-MAX™ PD8-6310 offers all the functionality of the ProVu PD6310 as a fully FM, CSA, ATEX, and IECEx approved explosion-proof product. It is a pulse input (NPN, PNP, TTL, switch contact, sine wave, etc.) digital batch controller specifically designed for single and multi-stage batching applications. It provides excellent but simple batch control capabilities with features such as preclose relays and automatic overrun correction for more accurate batches and convenient SafeTouch® through-glass buttons for simple operation and menu navigation without having to remove the cover. The preclose deactivates a specific relay before the batch is finished in order to allow slower fill rates and increased accuracy. Automatic overrun correction keeps the batch size accurate over time and with system wear. The PD8-6310 includes a 24 VDC power supply to drive the flowmeter and can be equipped with up to four internal relays and a 4-20 mA analog output.

| 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 kΩ 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. |
Pulse Input (continued)
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 seconds, 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. |
| Total Displays & Grand Total Overflow | 0 to 999,999; automatic lead zero blanking. “T” LED is illuminated while displaying batch total and “GT” for grand total. Up to 999,999,999 with total-overflow feature. “ ” is displayed to the left of grand total overflow and  LED is illuminated. |
| Batch Total Decimal Point | Up to five decimal places or none: d.ddddd, dd.dddd, ddd.ddd, dddd.dd, ddddd.d, or dddddd. Total decimal point is independent of rate decimal point. |
| Totalizer | Calculates total based on rate and field programmable multiplier to display total in engineering units. Time base must be selected according to the time units in which the rate is displayed. |
| Total Conversion Factor | 0.00001 to 999,999 |
| Batch Preset | 0.00001 to 999,999 based on batch total decimal point. |
| Automatic Batch Restart Delay | 00000.1 to 999.9 seconds. The batch will automatically restart after completion of the last batch. |
| 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. |
| Non-Resettable Grand Total | The grand total can be programmed as a non-resettable total by entering the password “050873”. Caution: Once the Grand Total has been programmed as “non-resettable” the feature cannot be disabled. |
Relays
| Rating | 2 or 4 SPDT (Form C) internal and/or 4 SPST (Form A) external; rated 3 A @ 30 VDC and 125/250 VAC resistive load; 1/14 HP (≈ 50 W) @ 125/250 VAC for inductive loads. |
| Noise Suppression | Noise suppression is recommended for each relay contact switching inductive loads. |
| Relay Assignment | Relays may be assigned to batch control, sampling, rate, or grand total alarms. |

| Alarm Relay Reset | User selectable via front buttons, digital inputs, or PC:
Note: Front panel button or digital input may be assigned to acknowledge relays programmed for manual reset. This replaces one of the standard batch control function keys. Only the PAUSE/STOP key function is possible during a batch process, so manual reset may only be done when the controller is in STOP mode. |
