1 Introduction

Statement of Intended Use – The M800 Multi-parameter transmitter is an online process instru­ment for measuring various properties of fluids and gases. These include conductivity, dissolved oxygen, O2 gas, dissolved ozone, dissolved carbon dioxide, pH / ORP, flow and turbidity. The M800 is available in different versions. The version indicates the amount of measurement pa­rameters which can be covered and the kind of parameter. The version are indicated through there part numbers on the label of the transmitter.
The M800 version with hygienic, polished stainless steel housing allows application in the field of biotechnology, food processing and in the pharmaceutical industry.

A colored touch screen conveys measuring data and setup information. The menu structure al­lows the operator to modify all operational parameters by using the touch screen. A menu-lock­out feature, with password protection, is available to prevent the unauthorized use of the meter. The M800 Multi-parameter transmitter can be configured to use up to eight analog and / or up to eight relay outputs for process control.
TheM800Multi-parametertransmitterisequippedwithaUSBcommunicationinterface.Thisin­terface provides up- and download capabilities of the transmitter configuration via a Personal Computer (PC).
This description corresponds to the firmware release, version 1.2. Changes are taking place constantly, without prior notification.

2 Safety instructions

This manual includes safety information with the following designations and formats.
2.1 Denitionofequipment
and documentation symbols and designations
WARNING: POTENTIAL FOR PERSONAL INJURY.
a
CAUTION: Possible instrument damage or malfunction.
a
NOTE: Important operating information.
h
On the transmitter or in this manual text indicates: Caution and / or other possible hazard includ-
ing risk of electric shock (refer to accompanying documents).
a
The following is a list of general safety instructions and warnings. Failure to adhere to these in-
structionscanresultindamagetotheequipmentand/orpersonalinjurytotheoperator.
a
– The M800 Transmitter should be installed and operated only by personnel familiar with
thetransmitterandwhoarequalifiedforsuchwork.
– The M800 Transmitter must only be operated under the specified operating conditions
(see chapter 15 “Specifications”). – Repair of the M800 Transmitter must be performed by authorized, trained personnel only. – With the exception of routine maintenance, cleaning procedures, as described in this manu-
al, the M800 Transmitter must not be tampered with or altered in
any manner. – Mettler-Toledo accepts no responsibility for damage caused by unauthorized modifications
to the transmitter. – Follow all warnings, cautions, and instructions indicated on and supplied with this product. – Installequipmentasspecifiedinthisinstructionmanual.Followappropriatelocalandna-
tional codes. – Protective covers must be in place at all times during normal operation. – Ifthisequipmentisusedinamannernotspecifiedbythemanufacturer,theprotectionpro-
vided by it against hazards may be void.
WARNINGS:
– Installationofcableconnectionsandservicingofthisproductrequireaccesstoshockhazard
voltage levels. – Main power and relay contacts wired to a separate power source must be disconnected be-
fore servicing.
– Switchorcircuitbreakershallbeincloseproximitytotheequipmentandwithineasyreach
oftheOPERATOR;itshallbemarkedasthedisconnectingdevicefortheequipment.
– Main power must employ a switch or circuit breaker as the disconnecting device for the
equipment.
– Electrical installation must be in accordance with the National Electrical Code and / or any
other applicable national or local codes.

NOTE: RELAY CONTROL ACTION
h
NOTE: PROCESS UPSETS
h
NOTE: This is a 4-wire-product with an active 4–20 mA analog output.
h
theM800Transmitterrelayswillalwaysde-energizeonlossofpower,equivalenttonor­mal state, regardless of relay state setting for powered operation. Configure any control system using these relays with fail-safe logic accordingly.
Because process and safety conditions may depend on consistent operation of this trans­mitter, provide appropriate means to maintain operation during sensor cleaning, replace­ment, or sensor or instrument calibration.
Please do not supply power to terminal 3 to 10 of TB1 and terminal 1 to 8 of TB3.

2.2 Correct disposal of the unit

When the transmitter is finally removed from service, observe all local environmental regulations for proper disposal.

3.3 Graphic Trend Measurement

Any single measurement may be displayed as a trend measurement over time. Measurement values will be indicated by a value on the Y-axis and time elapsed on the X-axis of the graph displayed. An actual measurement for the selected value will also be displayed numerically above the graphic trend display. The measurement value is refreshed once per second.
Graphic trending will only display the data within maximum/minimum range. Out of range val­ues or invalid values will not be displayed. The Y-axis will display the maximum value unit with its range; X-axis unit uses “mins” for minutes for measurements less than one hour and “hrs” for one day. 4 scales for X/Y-axis. The maximum value on Y-axis is one decimal place.
3.3.1 Activation Trend Display Screen
While the M800 displays the Menu Screen, touch any measurement value line of the display screen twice (1-chan, 2-chan, 4-meas, 8-meas) to activate the trend display for that measure­ment.
If a sensor is disconnected/connected a pop-up window come up; after closing the window, it will go back to the Menu Screen.
Red/yellow bar on top line will display for any message occurring during trending. ‘H’, ‘P’,”AB” will display when this channel is in hold or process.

NOTE: 1 h means: 1 meas storage/15 seconds, totally 240 measurements for 1h. 1 day
h
means: 1 meas storage/6 minutes, totally 240 measurements for 1 day;
Range: Option button
Default(default value) Individual
When “Default” modes are set for the maximum or minimum value, this indicates the full mea­surement range for this unit. A Max or Min button is not displayed. If setting is selectable, the user can set maximum and minimum settings manually.
Max: Edit button.
Maximum value of this unit on Y-axis. xxxxxx, floating decimal point.
Min: Edit button.
Minimum value of this unit on Y-axis. xxxxxx, floating decimal point. Max Value > Min Value
NOTE: Settings for Y-and Y-axis and the corresponding measurement values are stored the trans-
h
mitters memory. A power down returns to default settings.
3.3.3 Deactivation Trend Display Screen
Press H in activated graphic trend screen to return to Menu Screen.

4.2.2 Mounting Procedure – 1/2 DIN Version (PC housing)
1/2 DIN versions transmitters are designed for the following mounting versions: panal mount, wall mount or pipe mount. For wall mount the integral rear cover is used.
Optional hardware accessories are available that allow for panel- or pipe-mount. Refer to section „14.2 Accessories and Spare Parts“.
Assembly
Fig. 4: Assembly – 1/2 DIN version (PC housing)
1 1 piece M25 x 1.5 cable gland 2 4 pieces M20 x 1.5 cable glands 3 4 pieces screws
General:
– Orient the transmitter so that the cable grips face downward. – Wiring routed through the cable grips shall be suitable for use in wet locations. – In order to provide IP66 enclosure ratings, all cable glands must be in place. Each cable
gland must be filled using a UL rated cable marked “wet”, “wet location” or “outdoor”, mea­suring0.36”(6.6mm)orlargerdiameter,employedwithinthespecifiedstrainreliefclamp­ing range. Do not use metal conduit.
– Tightenthescrewsofthefrontpanelwithatighteningtorqueof2Nm.
Transmitter M800 26
4.2.3 1/2 DIN Version (PC housing) – Panel Mounting
To insure a good seal, the panel or door must be flat and have a smooth finish. Textured or rough surfaces are not recommended and may limit the effectiveness of the gasket seal provid­ed.
1. Make cutout in panel. For dimensions refer to 4.2.1 “Dimensions 1/2 DIN Version (PC
housing)”.
– Be sure surface surrounding cutout is clean, smooth and free of burrs.
2. Slide face gasket around transmitter from the back of the unit.
3. Place transmitter into cutout hole. Be sure there are no gaps between the transmitter
and panel surface.
4. Place the two mounting brackets on either side of the transmitter as shown.
5. While holding transmitter firmly into the cutout hole, push the mounting brackets toward
the backside of panel.
6. Once secure, use a screwdriver to tighten the brackets against the panel. In order to pro-
vide IP66 environmental enclosure rating, the two clamps provided shall be securely tight-
enedtocreateanadequatesealbetweenthepanelenclosureandtransmitter.
– Face gasket will compress between transmitter and panel.
