INTRODUCTION The CIP II converter is designed to work with oscillating piston flowmeters (COVOL) and turbine flowmeters series TM. The circuit is based on a microprocessor that, in function of the programmed pulses per unit of volume, totalizes the volume that flows through the meter and shows this value on the display.
OPERATION To adapt the converter to the meter, the pulses per unit factor specified on the meter must be programmed. To do this, the plastic front cover must be removed by unscrewing the four screws on the corners. After that, the push buttons will be accessible. There are three push buttons with the following functions: Programming By pushing the two push buttons PROG at the same time for at least two seconds, the...
In this mode there are 7 digits (five whole numbers and two decimals). The value that must be introduced is the pulses per unit factor given on the label of the COVOL or turbine. Depending on the volume units, the k factor should be programmed as follows: 1) litres: the k factor will be directly the value on the flowmeter label.
Counter overflow If one of the counters overflow, this condition is indicated at the right of the partial totalizer. If none of the counters has overflowed then this part of the display is blank. When one of the counters overflows then the display will show “A/B”, where “A” is the number of times that the partial counter has overflowed and “B”...
To correct these types of errors we can modify the pulses per litre factor programmed in the instrument. Example - Shortage of volume If we have a converter which specifies a k factor = 1.985, and when we check the volume of a batch, we find that instead of having 100 litres as programmed, we have 105 litres (5% more), we must apply the following correction: = k factor (original pulses per litre)
COVOL input characteristics This input is designed for a potential free contact between terminals 1 & 2 of the connector. Terminal 1 is connected to the common of the instrument. This input has a 1 MΩ pull-up resistor connected to terminal 1 and to the 3,3 V power supply. The input has a hysteresis with the switching points situated at about 1 V &...
SAFETY INSTRUCTIONS The series CIP II of programmable totalizers are in conformity with all essential requirements of all EC directives applicable to them: 2014/30/EU Electromagnetic compatibility directive (EMC) 2012/19/EU Waste electric and electronic equipment directive (WEEE). 2011/65/EU Directive relating restriction of the use of certain hazardous substances in electrical and electronic equipment (ROHS).
9.1.2 Connecting conductive parts to earth When the instrument is not grounded securely through the connection process, it should be grounded through the housing screw, as shown in the figure. Grounding screw 9.1.3 Maintenance NOTE: The cover should never be opened in presence of explosive atmosphere. There is no special maintenance for the ATEX version.
