PRO-FLO200

Flow Rate Totalizer

This sophisticated panel mount control-

ler is the ideal solution for a variety of

ow rate applications, and is designed

for simple setup and operation.

It features a customizable dual display,

user programmable input functions,

and simple calibration using K factor en-

try, or pulses per unit of measurement.

Advanced setpoint modes are available,

including timed or latched types, and

the totalizer features batch counting

and volumetric pulse.

2.1 - Advanced Setpoint Types

There are three setpoint types available for this model:

› A normal setpoint will activate and deactivate using alarm or control logic (see

8.2J) regulated within a hysteresis band (see 8.2K).

› A timed setpoint will activate as normal, and remain active for a user defined

time period (see 8.2O), after which it will deactivate automatically.

› A latched setpoint will activate as normal, and remain active until it is unlatched

either by setpoint logic (see 8.2Q), or manually using a user shortcut pin/key

(see 7.6).

2.2 - Batching

This function allows the Total count to be maintained, as well as the current batch

value. This allows the user to maintain the total in the background, while still allow-

ing set batch amounts to be measured. The batching feature uses the calculation: Batch = Total – Batch Tare.

Batch Tare is reset to the Total value when a reset batch function is triggered via

setpoint logic (see 8.2Q) or a user shortcut pin/key (see 7.6).

Batch Count allows the user to count how many completed batches have been pro-

cessed. The Batch Count Modier (see 8.2U) value (usually 1 or -1) is added to

the Batch Count register each time the Batch Setpoint is activated, as per the

selected Reset Edge (see 8.2S).

2.3 - Input Signal Averaging

Input signal averaging reduces noise and optimizes stable measurement.

If your input signal contains large noise spikes, you can increase the size of the aver-

aging window to ensure that these are still averaged. If the change in input exceeds

the averaging window value it will not average, ensuring fast response when there

are large dierences between readings. Increasing the window size too far will re-

duce the ability of the controller to respond quickly to real changes in input signal.

2.4 - Startup Inhibit

This feature can be used with setpoints which may be active initially at power up. It

will cause a relay to remain o (de-energized) at power up until it has rst reached

its inactive state, aer which it will function normally.

2.5 - Volumetric Pulse

This function is ideal for feeding volume information to other equipment. It outputs

a pulse on the relay when Total ≥ Setpoint Value, causing the relay to activate for a

specied length of time (see 8.2G), which can be adjusted to suit the requirements

of externally connected devices.

When a setpoint is activated in volumetric pulse mode, the totalizer will reset using the calculation: Total = Total – Setpoint Value, and then resume totalizing.

Used to access the Setpoint Setup menu (Section 8) and the Setpoint Direct

Access menu (Section 9).

3.2 - Display brightness

To adjust the display brightness, press the and buttons together from the main display. BRI appears and toggles with the current setting. Use the and

buttons to adjust the LED backlight, and then press to return to the normal

operating mode.

3.3 - Up and down button shortcuts

Pressing the and buttons from the main operational display allows instant

access to a number of values held in the controller's memory. These variables will ap-

pear in the order shown in the table below, and will cycle continuously at each press

of the or button.

Press

at any time to return to normal operating mode. The PEAK, VALLEY, TO-

TAL and BT CNT values may be reset to zero by pressing the and buttons at the same time while the variable is being displayed.

Up and down button shortcuts

RATE The current ow rate input

BATCH The batch value

PEAK The maximum measured ow rate input since the instrument was turned on

or reset

TOTAL The totalizer value

BT CNT The number of batches that have been processed (batch count)

INFLIT Inight correction oset: This value is calculated by the controller based on

the batch error (the dierence between the batch setpoint value and the nal batch value) averaged over the last three batches, and the Inight Adjustment Delay time (selected in 8.2W)

VALLEY The minimum measured ow rate input since the instrument was turned on

or reset

BEFORE YOU BEGIN WIRING, ensure that the unit is switched o and the power supply is disconnected.

IMPORTANT: The input module for this unit has four headers which are factory congured to suit your application. The unit is congured for an NPN type sensor by default.

¨ If you are using an NPN type sensor, you don't need to change anything.

¨ If you are using PNP, TTL, Namur, Tacho, or a Pushbutton switch, please

review your header configuration before continuing, referring to Section 6.

Then wire your input as required, referring to the diagrams on the following page.
