1 Introduction

Statement of Intended Use – The M300 for ISM transmitter is a single or dual- channel online process instrument for measuring various properties of ﬂuids. These include Conductivity*, Dissolved Oxygen and pH/ORP. It will interface with ISM (Intelligent Sensor Management) sensors from Mettler-Toledo, which connect to the transmitter using cables of varied lengths. The transmitter features the Plug and Measure functionally. That means the calibration and conﬁguration data of each ISM sensor are stored in the sensor head and will be uploaded to the transmitter after connection. * Q4/2008

A large four line backlit Liquid Crystal Display conveys measuring data and setup information. The menu structure allows the operator to modify all operational parameters by using keys on the front panel. A menu-lockout feature, with password protection, is available to prevent the unauthorized use of the meter. The M300 Multiparameter transmitter can be conﬁgured to use its four analog and/or six relay outputs for process control.

The M300 Multiparameter transmitter is equipped with a USB communication interface. This interface provides real-time data output and complete instrument conﬁguration capabilities for central monitoring via Personal Computer (PC).

Up to 6 Setpoints can be conﬁgured on any of the measurements (a thru d). The possible Setpoint types are Off, High, Low, Outside and Between.

An ‘Outside’ Setpoint will cause an alarm condition whenever the measurement goes above its high limit or below its low limit. A ‘Between’ Setpoint will cause an alarm condition to occur whenever the measurement is between its high and low limits.

Enter the desired value(s) for the Setpoint and press [ENTER]

This screen provides the option to conﬁgure a setpoint to be active on an over range condition. Select the setpoint and ‘Yes’ or ‘No’. Select the desired relay that will activate when the setpoint alarm condition is reached.

Over Range Once conﬁgured, the selected relay will be activated if a sensor over-range condition is detected on the assigned input channel.

Delay

Enter the delay time in seconds. A time delay requires the setpoint to be exceeded continuously for the speciﬁed length of time before activating the relay. If the condition disappears before the delay period is over, the relay will not be activated.

Hysteresis Enter the hysteresis as a percentage-value. A hysteresis value requires the measurement to return within the setpoint value by a speciﬁed percentage before the relay is deactivated.

For a high setpoint, the measurement must decrease more than the indicated percentage below the setpoint value before the relay is deactivated. With a low setpoint, the measurement must rise at least this percentage above the setpoint value before the relay is deactivated. For example, with a high setpoint of 100, when this value is exceeded, the measurement must fall below 90 before the relay is deactivated.

Hold Enter the Relay Hold Status of ‘Last’ or ‘Off’. This is the state the Relay will go to during a Hold status.

State

Relay contacts are in normal state until the associated setpoint is exceeded, then the relay is activated and the contact states change.

Select ‘Inverted’ to reverse the normal operating state of the relay (i.e. Normally open contacts are in a closed state, and normally closed contacts are in an open state, until the setpoint is exceeded). ‘Inverted’ relay operation is functional when power is applied to the M300 transmitter.

10 PID Setup

(PATH: Menu/PID Setup)

PID control is proportional, integral and derivative control action that can provide smooth regulation of a process. Before conﬁguring the transmitter, the following process characteristics must be identiﬁed.

Identify the control direction of the process

– Conductivity: Dilution – direct acting where increasing measurement produces increasing control output

such as controlling the feed of low conductivity diluting water to rinse tanks, cooling towers or boilers

Concentrating – reverse acting where increasing measurement produces decreasing control

output, such as controlling chemical feed to attain a desired concentration

– Dissolved Oxygen:

Deaeration – direct acting where increasing DO concentration produces increasing control

output such as controlling the feed of a reducing agent to remove oxygen from boiler feedwater

Aeration – reverse acting where increasing DO concentration produces decreasing control

output, such as controlling an aerator blower speed to maintain a desired DO concentration in fermentation or wastewater treatment

– pH/ORP:

Acid feed only – direct acting where increasing pH produces increasing control output, also

for ORP reducing reagent feed

Base feed only – reverse acting where increasing pH produces decreasing control output,

also for ORP oxidizing reagent feed

Both acid and base feed – direct and reverse acting

Identify the control output type based on the control device to be used: Pulse Frequency – used with pulse input metering pump Pulse Length – used with solenoid valve Analog – used with current input device such as electric drive unit, analog input metering

pump or current-to-pneumatic (I/P) converter for pneumatic control valve

Default control settings provide linear control, which is appropriate for conductivity, dissolved oxygen. Therefore, when conﬁguring PID for these parameters (or simple pH control) ignore settings of deadband and corner points in the Tuning Parameter section below. The non-linear control settings are used for more difﬁcult pH/ORP control situations. If desired, identify the non-linearity of the pH/ORP process. Improved control can be obtained if the non-linearity is accommodated with an opposing non-linearity in the controller. A titration curve (graph of pH or ORP vs. reagent volume) made on a process sample provides the best information. There is often a very high process gain or sensitivity near the setpoint and decreasing gain further away from the setpoint. To counteract this, the instrument allows for adjustable non-linear control with settings of a deadband around the setpoint, corner points

11.2.2 Calibrate Analog

Select the Analog Output you wish to calibrate. Each Analog output can be calibrated at 4 and 20 mA.

Connect an accurate milliamp meter to the Analog output terminals and then adjust the ﬁve digit number in the display until the milliamp meter reads 4.00 mA and repeat for 20.00 mA.

As the ﬁve digit number is increased the output current increases and as the number is decreased the output current decreases. Thus coarse changes in the output current can be made by changing the thousands or hundreds digits and ﬁne changes can be made by changing the tens or ones digits.

Pressing the [ENTER] key after entering both values will bring up a conﬁrmation screen. Selecting No will discard the entered values, selecting Yes will make the entered values the current ones.
