ME995-7
LITRES PRESET BATCH CONTROLLER
DATASHEET
FEATURES
4-Digit LED display.
4 LED status indicators.
Preact function.
Preset maximum limit.
Missing pulse detection.
Counts in Litres upto 9999.
Optional PLC and computer interface.
Signal conditioning, with K-factor.
Compatibility with most flowmeters.
The ME995-7 LITRES preset Batch Controller can be used with most pulse output flowmeters, for preset liquid batch
control applications.
The controller incorporates a preact (overflow deduct) feature, K-factor adjustment, 4 LED status indicators and
diagnostic safeties. With the ME995-7 Batch Controller using the same 10-pin Weidmuller receptacle plug as the previous
models, making changeover or upgrade instant with no rewiring necessary. It can be easily interfaced with PLCs, thus
incorporating the controller's safety features and providing a backup batch facility.
With 4 rotary selector switches, batch quantities are easily selected. The batch operator can also visually refer to the
numbered selector dials for the selected batch quantity. Command operations are by user-friendly toggle switches, and
four LEDs indicate operational status conditions.
Batch counting is in 1 Litre increments, up to a maximum 9000 Litres.
The controller operates from standard 220 - 260 vac (or optional 24vac, 110vac or 12 - 24 VDC) voltage supplies.
Contact output drive is via one (or optional two) relays. (or with –OC open contact drive to allow control output switching
drive of any external voltage). Standard controllers are in panel mount form, or optionally can be housed in a metal box or
IP65 ABS wall mount enclosure.
The ME995-7 controller is designed for compatibility with ManuFlo flowmeters and many other types.
Calibration for the desired flowmeter is selectable via the rear dials.
SAFETY FEATURES
*
LIMIT (LM) LED
activates if batch cycle reaches locked internal limit or if circuit diagnostics detect internal chip
problem. There is subsequent automatic shutoff of voltage contact drive.
*
PULSE FAIL (PF) LED
activates if no pulses arrive within 1.5 seconds (variable) initial start time period, or if pulses are
interrupted during batch cycle and fall below (variable) pulse scanning time (typical 30Hz). There is subsequent
automatic shutoff of voltage contact drive output.
*
FLOW (FL) LED
monitors and indicates incoming pulses from field flowmeter, or if TEST is used.
*
CONTACT DRIVE (CD) LED
indicates voltage contact output drive when pump or solenoid are activated.
* Internal audible
ALARM
sounds momentarily upon completion of batch cycle, and continuously if PULSE FAIL or LIMIT
LEDs are activated or if overflow runs 26 litres over selected batch quantity.
