HML 110 ELECTRICAL CONNECTIONS GROUNDING INSTRUCTIONS ALWAYS ensure that the Converter and the Sensor are grounded (earthed) correctly. The grounding of the sensor and converter ensures that the equipment and liquid are equipotential. CONVERTER POWER SUPPLY Before connecting the power supply, verify that the L(-) N(+) mains voltage falls between the limits indicated on the tag plate. ATTENTION: Converters on a dc power supply line are not protected against the inversions of polarity.

HML 110 DISPLAY FLAGS AND LED WARNING INTERPRETATION At ‘Power on’ of the converter, the user will see the following display screen. In the top right hand corner there may be a range of symbols. The symbols can be interpreted from the table below.
HML 110 M3 ACCESS TO THE CONVERTER KEYPAD KEYBOARD The keypad is accessible by loosening the 4 cover screws, and opening the front cover of the converter. Three KEYS are set aside of the M1 terminal block allowing the user to change screen display visualizations and select functions.
HML 110 ACCESSING THE CONVERT FUNCTIONS AT START-UP (Power On) Example of visualized display pages at start-up The direct exposure of the converter to the solar rays, could damage the liquid crystals display. Active scale Alarm on Flow rate visualization Note: The user will see the screen displayed (left) at power on of the converter. Use the keys on the keypad as indicated centrally on this page to move between the screens shown (not all shown).
HML 110 FLOW RATE VISUALIZATION The ML110 allow showing 5 digit character display for flow rate units. This mean the maximum flow rate value that can be represent on the display is 19999* (no matter the positioning of the decimal point ) and the minimum is 0.025.
HML 110 CONVERTER FUNCTION SETTING ACCESS CODES User defined access codes Factory preset access The converter is delivered with the default L2 (level 2) access code. The code if required for accessing ‘Main menu’ functions from the ‘Quick start menu’. 11111 Functions in the converter’s ‘Main menu’ are enabled by the access codes. The information of this manual is related to all the functions available with in the L2 level. All higher level functions are reserved for servicing and not available.
HML 110 EXAMPLE: “Quick start menu” function modification. Full scale value 1 (Fs1) from 4dm³/s to 5dm³/s.
HML 110 EXAMPLE: “Main menu” function modification. Full scale value 1 (Fs1) from 4dm³/s to 5dm³/s.
HML 110 MAIN MENU GROUPS AND FUNCTION DESCRIPTIONS. The main menu is selected from the Quick Start Menu by pressing the key) and entering the factory code(11111). Functions denoted in grey are displayed only with other active functions, or with optional modules. (for details of the functions with the symbol “*” refer to pages 22-27). Not all the functions displayed on the converter are shown below are reserved for serving purposes only and not configurable. 1.

In reality there is always a minimum time between the measure acquisition and the outputs update. (POS. 3.3) Peak cut off threshold [Peak thr=% XXX] Anomalous signal peak cut off threshold set. This parameter allows for setting the maximum value of deviation of the measured sample in comparison to the average.
HML 110 The NAMUR NE43 recommendations requires alarms signaling value for a current output lower than 3.6 mA (<18%) or greater than 21 mA (>105%). It is preferable to set the value of this function at 10%, so that the current value in cases of a.m.
HML 110 (POS. 6.3) Duty cycle value for pulses/frequency output [Duty cycle=% XX] The duty cycle function defines the time ratio between ON and OFF state when frequency output is used: 50% means that the ON phase will equal that of the OFF phase, 60% means that the ON phase will be 60 % and the OFF phase will be 40% of the total cycle time.
