INTRODUCTION
The ME697 counter divider interface card was designed to act as a support product in interfacing upto six ManuFlo
admixture 20mm pulse output flow meters ( MES20, KGG20, MEK20 ) with Eagle and other USA industrial computer
systems, requiring low frequency pulse rates and 110-240vac pulse inputs. This new design incorporates new high
resolution missing pulse and maximum batch limit overrides, as well as a six-channel manual batching facility.
FUNCTION
The computer system provides an AC output start and hold drive signal (black Opto22) to ME697 start input. The
ME697 output drive supplies power to external contactor coils driving pumps and/or solenoids. ME697 supplies
+12VDC to flowmeters which in turn send back pulses which are counted by individual channel LCD displays in
millilitres. The pulses are then sent to the computer inputs (yellow Opto22). When the computer system has OPTO22,
110 - 240 vac input optos, incoming pulses are limited to 14 Hz maximum. Due to high resolution pulsing of
flowmeters, the pulse rates must be divided. The onboard selectable dip switches are then set to the desired pulse
division rate (see Fig.1).
The divided output pulses are indicated by the pulse LEDs. The pulses are stepped up (via Motorola MOC3041 Triacs)
to 110 - 240 vac switching pulses. These pulses arereceived by the computer input card (through Yellow OPTO22).
When computer has completed batch cycle, a 110 or 240 vac reset signal is supplied to the ME697 master reset relay,
thus reseting all counters.
SAFETY OPERATION
If, at any time during batch cycle, any flowmeter stops pulsing (e.g. due to flow obstruction, failure, blockage, pump
failure etc), or the preset upper safety limit is reached, the inbuilt Pulse Fail feature will activate, shutting down flow
regardless of computer's status operation. If Pulse Fail (P.F.) is activated, warning LED(s) will illuminate, indicating the
channel at fault. Also, an audible alarm will sound. If upper batch limits are set, and if they are reached, the same
safety features will activate. If channel(s) pulse failed, remember the quantity displayed. Reset unit to resume batching.

ME697 (Eagle version)
OPERATION To batch in manual mode (without computer) :
•Switch on power. Reset or zero counters by pushing the reset button.
•Push and hold one (or more) of the six run buttons. When the desired amount is reached, release button.
You can also batch from the computer’s manual mode at console panel.
•When batching automatically (computer mode), do not touch reset or run buttons.
•If alarm activates, always cross-reference ME697 and computer screen displays to see if they are corresponding in
the quantity dispensed.
*********************************************************************************************************************************
If Pulse Fail (P.F.) occurs repeatedly and alarm sounds, do not persist - qualified service or advice is required.

INSTALLATION
1. Find a suitable position to wall-mount box - consider good view of LCDs and room for wiring.
The ME697 is fixed to the cover lid, therefore cable gland entries can be fitted to box at any location.
2. Use at least a 10-core shielded cable for flowmeters. Wire flowmeter cable to 8-pin (J4) flowmeter input plug,
taking care to observe correct channel (1-6) identification, and that wiring to + and - terminals is correct.
3. Connect 240vac supply to 3-pin plug (J5).
4. Connect from 7-pin plug (J1), AC pulse output drives to computer's yellow OPTO22 pulse inputs.
5. Connect from 8-pin (J2) input start and master reset plug, to 6 x computer black Opto22 output start drives and
1 x master reset opto located in computer I/O panel.
6. Wire from 7-pin plug (J3) output drive plug, to external contactor coil and/or solenoid flow control drives.
Make sure only one common active line and neutral is used to interconnect wiring on ME697 card, from the computer
supply. Do not mix active pump drive with computer's Uninteruptable Power Supply (UPS).
NOTE: Neutral J2 and J5 is already bridged internally.
J5 active line after switch and fuse is bridged to J1 Active and J3 Active. Only wire A.N.E. J5 power input plug.
* Six wires from J1 to computer yellow Opto22 (pulses).
Seven wires from J2 to computer black Opto22 (six start drives, one master reset).
From J3, six wires will drive each contactor coil, return neutral to J2 neutral.
From J4, wire six pulse wires, one +12V, one O.V. or shield to flowmeters.

ME697 Troubleshooting
• keep input rate to AC Computer/PLC below 15 Hz (otherwise overdose could occur due to computer missing pulses).
• if the ME697 appears disabled (e.g. displays read zero, does not count, no functions even in manual mode) then the
Master Reset black Opto on the PLC is leaking, or is stuck on causing a continual reset drive to the ME697.
Measure the leakage voltage between the Master Reset (Connector J2, pin 7) and Neutral (Connector J2, pin 8). If
there is more than 60vac voltage, then:
oreplace the Black Optos; and/or
ofit a 12-15 KΩ10W resistor between the Master Reset and Neutral (i.e. between pins 7 and 8 of Connector J2).
If there is still a problem, then it is a Computer issue that the master reset is stuck on. Disconnect the plug connecting
the Computer to J2 and batch manually.
•if the batching computer’s black Optos are leaky (i.e. there is more than 60vac residual voltage after Opto latches off,
which could cause batching to continue because the ME697 relay is being held on), then:
oreplace the Black Optos; and/or
ofit a 12-15 KΩ10W resistor between each black Opto’s Active 240vac Computer Start (i.e. relevant pin on
connector J2) and Neutral (pin 8 on Connector J2).
• if experiencing slow counts on one channel after batch completes: ensure that Check Valve is not faulty.
• if experiencing phantom counts on one channel: check wiring and shield.
•if experiencing constant phanton counts on many channels: the internal 1000 μF electrolytic capacitor may have
failed, so return the ME697 to ManuFlo for service.

INSTALLATION GUIDE for ME697 Interface Card
with MES20 and other flowmeters
(1) Locate the most appropriate position to mount the MES20 flowmeter. Preferably:
•your site’s flowmeters should be grouped together off the ground on a stand.
•protect the flowmeters from the elements by using a cover, which should be lightweight with handles for easy access
by service personel.
•a vibration free area is recommended, as the MES20 is sensitive to high vibrations which can cause some stray
pulses (see the “Installation” section in the MES product brochure).
(2) Establish the outlet point position in relation to the storage tank:
2a) If the outlet point is above the top of the storage tank (the most commonly used setup), then
the equipment you will need is at least: a pump, non-return valves or spring loaded check valves (12psi), flow
restriction gate or ball valve, a flowmeter with pulse output and, optionally:
•a solenoid valve (air-assisted ball valve type) for instant shut off of flow, recommended to prevent the Venturi effect
when injecting into water lines, but may not be required if the installation has reasonable head height.
•a 3-Way Valve to provide an easily accessible calibration point.
