Mathematics

With the mathematics package, measured values of the inputs or the results of other math channels can be linked mathematically. A formula with up to 200 characters can be created using a formula editor. Once entered, the user can then check the plausibility of the formula.

Functions:

•12 math channels

•Mathematics functions via formula editor

•Basic arithmetic operations, relational operators, logic operations and functions

Telealarm software

The Telealarm software facilitates user mobility, allowing users to respond to events while they are on the road. E-mails or SMS messages triggered by process alarms or other important process events can be sent to several recipients simultaneously or automatically forwarded to a recipient/ destination. Messages can be confirmed, relays controlled remotely and current values queried by cellular phone. The Advanced Data Manager with GSM (GPRS) or Ethernet is ideal both for environmental applications to monitor unstaffed outstations, and for tank monitoring applications.

The Telealarm software contains the mathematics package. Functions:

•Advanced SMS/e-mail notification in the event of an alarm

•Instantaneous values queried by cellular phone

•Remote relay switching

•Alarm confirmation by SMS

Batch software

Batch management allows users to reliably record and visualize discontinuous processes. Userdefinable or externally controlled analysis intervals are possible for up to four batches simultaneously. Batches are assigned batch-specific values and the measured data, the start, end and duration of every batch, along with the current batch status, are displayed on the device and in the Field Data Manager software. At the end of the batch, batch information is automatically printed out directly at the device (USB or network printer) or is printed out via a PC with the Field Data Manager software.

The batch software contains the mathematics package. Functions:

•Batch report for 4 batches simultaneously

•USB barcode reader

•Automatic batch printout

•Preset counter

Wastewater + RSB (rain spillway basin)

The water/wastewater software supports operations monitoring of the water/wastewater sewage network to obtain information about the quality and efficiency of the plant. The daily, weekly, monthly and yearly maximum and minimum value is determined per quantity channel. Infiltration water recording and the monitoring of rain spillway basins for reservoir and overflow events are also functions of this software option.

The water/wastewater software contains the mathematics package and the telealarm software. Functions:

•Rain spillway basin (reservoir/overflow)

•Highest and lowest values for quantities

•Highest and lowest values from ¼-hourly averages

•Determination of infiltration water

Energy package (water + steam)

The energy package allows users to calculate the mass and energy flow in water and steam applications on the basis of the flow, pressure and temperature (or temperature differential). Furthermore, energy calculations are also possible using glycol-based refrigerant media.

By balancing the results against one another or by linking the results to other input variables (e.g. gas flow, electr. energy), users can calculate overall balances, efficiency levels etc. These values are

important indicators for the quality of the process and form the basis for process optimization and maintenance.

The internationally recognized standard IAPWS-IF 97 is used to calculate the thermodynamic state variables of water and steam.

In the energy software, it is also possible to compensate differential pressure flow measurement ("DP-Flow"). The calculation of flow based on the differential pressure method is a special form of flow measurement. Volumes or mass flow rates that are determined using the DP method require specific correction. By solving the calculation equations listed in the standard in an iterative manner, highly accurate results for DP flow measurements can be achieved. The measurement (orifice plate, nozzle, Venturi pipe) is performed in accordance with ISO5167. Flow measurement based on the dynamic pressure method uses the interrelation between differential pressure and flow.

The energy package contains the mathematics package.

Additional functions:

• 12 math channels

(Channels 1-8: energy-specific formulas and formula editor, channels 9-12: formula editor)

• Heat quantity + mass calculation for water and steam applications

• Efficiency calculation

Device error/alarm relay

One relay can be used as an alarm relay. If the device detects a system error (e.g. hardware defect) or a fault (e.g. cable open circuit), the selected relay switches.

This "alarm relay" switches if the device status is "F" (Failure). If the device status is "M" (Maintenance required), the alarm relay does not switch.

	Safety
	Recorded data are saved in a tamper-proof format and can be exported and archived with
	manipulation protection using the Field Data Manager software.
IT security	The manufacturer only provides a warranty if the device is installed and used as described in the
	Operating Instructions. The device is equipped with security mechanisms to protect it against any
	inadvertent changes to the device settings.
	IT security measures in line with operators' security standards and designed to provide additional
	protection for the device and device data transfer must be implemented by the operators themselves.

	Input
Measured variables	Analog universal inputs
	Standard version without universal inputs. Optional multifunction cards (slot 1-5) with 4 universal
	inputs (4/8/12/16/20) each.
	You are free to choose between the following measured variables for each universal input: U, I, RTD,
	TC, pulse input or frequency input.
	Integration of input variable for totalization e.g. flow (m3/h) in quantity (m3).
	HART® inputs
	Standard version without HART® inputs. Optional HART® input cards (slot 1-5) with 4 inputs
	(4/8/12/16/20) each.
	Both the digital HART® values and the 4 to 20 mA signal can be evaluated at every input.
	The 4 HART® values (PV, SV, TV, QV) of a sensor can be evaluated and the analog HART® value (PV)
	can be measured via the digital HART® signal. Up to 40 digital HART® values can be recorded in
	total. It is possible to access the HART® sensor in the field from a PC tool (e.g. FieldCare). In this way,
	the sensor can be configured from the control room and the status information of the sensor can be
	analyzed/displayed. The Memograph M acts as a HART® Gateway.
	Access to the connected sensors is only possible if the device is connected by Ethernet.
	Port 5094 must be open in the firewall.
	Digital inputs
	Standard version: 6 digital inputs
	Optional digital card (slot 5): 8 additional digital inputs, 6 additional relays and 2 analog outputs

	output
	1)	Test voltage applies between inputs on power unit (terminals D11 to D61) to inputs on optional digital
		card (terminals D71 to DE1). The inputs are galvanically connected on the same plug-in connector.
Cable specification	Cable specification, spring terminals
	All connections on the rear of the device are designed as pluggable screw or spring terminal blocks
	with reverse polarity protection. This makes the connection very quick and easy. The spring
	terminals are unlocked with a slotted screwdriver (size 0).

Please note the following when connecting:

•Wire cross-section, auxiliary voltage output, digital I/O and analog I/O: max. 1.5 mm2 (14 AWG) (spring terminals)

•Wire cross-section, mains: max. 2.5 mm2 (13 AWG) (screw terminals)

•Wire cross-section, relays: max. 2.5 mm2 (13 AWG) (spring terminals)

•Stripping length: 10 mm (0.39 in)

No ferrules must be used when connecting flexible wires to spring terminals.

Shielding and grounding

Optimum electromagnetic compatibility (EMC) can only be guaranteed if the system components and, in particular, the lines - both sensor lines and communication lines - are shielded and the shield forms as complete a cover as possible. A shielded line must be used for sensor lines that are longer than 30 m. A shield coverage of 90% is ideal. In addition, make sure not to cross sensor lines and
