DESCRIPTION

MC20D Smart Universal Pressure Transmitter is a cost efficient general purpose pressure transmitter. Each unit is constructed of stainless steel for durability in severe environments. Both gas and liquid pressure overloads of up to 200% over capacity are safely accepted. The MC20D provides accurate, stable, and reliable pressure measurement in difficult applications. Its small compact design allows it to be directly connected to a process. The MC20D features a fully configurable LCD that displays pressure and diagnostic information. The information displayed is directly from the microprocessor which accounts for its accuracy and reliability.

INSTRUCTIONS

1. HART operator may be connected to the circuit （4-20mA） for monitoring the pressure transmitter or setting operations (see HART operator manual).

2. The use instruction for the button on the transmitter’s LCD display:

Zero and Span Shift

Zero Shift: Simultaneously presses down the S key and the Z key (left side is the S key, right side is the Z key) for 6 seconds, display shows “Hart” which indicate that zero and the range adjustment has bee activated. Presses down the Z key for 5 seconds, the character of “Hart” vanish. Zero shift finished and the state of activation is withdrawal.

Span Shift: Simultaneously presses down the S key and the Z key (left side is the S key, right side is the Z key) for 6 seconds, display shows “Hart” which indicates that zero and the range adjustment has bee activated. Confirming the right pressure corresponding to 20mA, then presses down the S key for 6 seconds, the character “Hart” vanishes, span shift finished at that time and the state of activation is withdrawal.

Note: After entering the state of activation, if not want to make the adjustment, simultaneously presses down the S key and the Z key. After loosening the key, the character of “Hart” on the display vanishes and the state of activation is withdrawal. (Switching on the power again can achieve the same result)

Parameter settings

Press the S key for 6 seconds, the display shows "PASS", then press Z key and the display shows the value. Flicker bit is the modified bit. Press the Z key to add one to the bit. Press Z key for 4 seconds the cursor shift. First operating in the way as above to to modify the value into 160, then press S key to enter the next parameter of the adjustment process. The meaning of each parameter is as follows:

Character	Value	Meaning
	*XXXXX*	Password，the value is 160
BDSH	*XXXX.X*	Span shift corresponding to 20mA
BDSL	*XXXX.X*	Zero shift corresponding to 20mA
TRAN	*XXXXX*	Transmitting function，=0: Linear output，=1: Evolution output
UNIT	*XXXXX*	Unit on display，0=KPa，1=KPa，2=KPa，3=KPa，4=KPa，6=Psi，7=bar，8=KPa，9=KPa，11=Pa，12=Kpa， 13=Kpa，15=MPa，16=mA，17=％，18=S，19=m3，20=t/h
DAMP	*XXXX.X*	Damping time, The maximum value is 30 seconds
PREL	*XXXXX*	*Low-*point fine-tuning: Adjusting the volume to the current process input values. Pressing Z key then modifying the fine-tune low point pressure. Do not press the Z key if not want to make adjustment. Pressing the S key directly to the next parameter
PREH	*XXXXX*	*High-*point fine-tuning: Adjusting the volume to the current process input values. Pressing Z key then modifying the fine-tunehigh pointpressure. Do not press the Z key if not want to make adjustment. Pressing the S key directly to the next parameter
INIT	*yes/no*	*Hart* *Three-points* *linearization* *and* *fine-tuning* *data initialization*

Note: Please be cautious when operating the parameters in italics. Ensure the pressure imposed by the device to be accurate.

NOTES

1. Please check the signs before installation to conform that the product model and the power supply range and is consistent with the scene;

2. Power should be stable voltage source;

3. In order to avoid solid deposits or other viscous material deposition into the pressure transducer hole, it is recommended to installation should be vertical down (or downward-sloping at an angle);

4. In the measurement of high-temperature media, please use the joining pipe or cooling heat sink, the temperature dropped to the use of transmitter range;

5. For outdoor installation, the transmitter should be kept dry and ventilated place, avoid direct light and rain;

6. When tWhen transmitter range ≤ 5KPa, the installation location will affect the zero point output; you need to adjust the zero point output after product installation.
