320 - Batch controller

320 - Batch controller
with multiple preset values and full process monitoring

The 320 batch controller is the most popular model in the 300-Series range. It offers comprehensive functionality to control and monitor your batching process perfectly. Four or fourteen different preset-values can be entered. These are easily selected with the arrow shaped keys or via the external inputs by a switch or PLC, allowing you to control the unit remotely. This way, operator error is reduced to a minimum, even for less skilled operators. To flush your pipes, valves and flowmeter, manual control of the relays is available. With the repeat function, a new batch can be started automatically within 15 minutes after the last batch. The calibration procedure makes re-calibrating of the flowmeter very convenient. All functions are software controlled and offer broad application areas and user-friendly control.

Features
• Four or fourteen preset values
• Monitor functions for: flow rate, total quantity, number of batches, leakage, process-time, batch-size, power-down.
• Automatic restart function for repeatet batch control.
• Manual flush-control.
• Record of total quantity batched with alarm set-point.
• Record of number of batches executed with alarm set-point.
• Calibration procedure for the flowmeter.
• Full numerical keyboard with twenty industrial micro-switch keys.
• User-friendly operation with clear menu structure.
• Self learning overrun correction.
• Two-stage control.
• Four styles of housing are available. Wall-mount housing comes as standard.

Applications

Alternative basic models: F030, F130, F131, 310.
Alternative advanced model: 326.

Flowmeter Inputs
• Reed-switch.
• NAMUR.
• NPN/PNP pulse.

Status Inputs
• Remote control: start / pause / stop / alarm.
• Remote control: preset selection 1-4 or 1-14.

Pulse Outputs
• Function: Scaled pulse output according to accumulated total (e.g. one pulse every 3.25 gallons).
Max. frequency: 10Hz.
Remark: with pulse output one-stage control only.
• Type: One isolated electro-mechanical make-and-break relay or one passive DC solid-state relay.

Alarm Outputs

Analog Outputs
• Function: Re-transmitting the flow rate - the output can be scaled to any range (e.g. 200 L/min to 1200 L/min).
• Type: One passive isolated 4 – 20mA output.

Control Outputs
• Function: Control outputs for one- or two-stage batching with active overrun correction.
Remark: with pulse output one control only.
