measurement requirements of CLEAN ROOMS in Pharmaceutical industries. The Process Monitor can

measure Relative Humidity, Temperature and Differential Pressure through inbuilt sensors. It has on

demand dew point display. The Monitor has status LEDs for process violation indication. Humidity,

Temperature and pressure will display individually and data transfers to any master device on modbus

serial communication. It also has communication diagnosis LED. The monitor has inbuilt buzzer for

audible process violation. It has keypad to programming the instrument by user. It has Stainless steel

Modular Face plate, which is designed as a mounting accessory for monitor suited for Modular wall Clean

Room applications where you need flush mounting mechanism. This instrument enables you to measure

humidity, temperature and differential pressure in the following fields:

HVAC (Heating, ventilation, Air conditioning, cooling)

Pharmacy industry.

Blood stations, pharmacies.

8. Instrument Operation

8.1. Functionality

Process Monitor has different modes of working. Description of each mode is given below:

a. Measurement mode: Measurement mode is default mode for Instrument. In measurement mode

instrument displays process values of three process parameters in respective display section.

b. Configuration mode: When PRG Key pressed in measurement mode causes to enter into

configuration mode. In configuration mode, we can configure/change the several key parameters

including instrument calibration. In detail will discuss in section 8.3.

c. Violation mode: When process value of any one of three parameters exceeds the set limits range,

Instrument will enter into violation mode measurement mode. In violation mode violated process

parameter display section will starts flashing, while flashing parameter enables, and respective



status LED becomes glow in red color and buzzer also becomes ON, while buzzer control

parameter ON.

d. Auto Zero Calibration mode: Hold the OK key for 5 sec causes to enter into auto zero calibration mode

from measurement mode. In this mode present differential pressure value will take it as zero offset.

Every unit has its own zero offset value. This mode indicates with ZERO display in place of

differential pressure display section. This mode remains for 5 sec only then it automatically comes

back to measurement mode.

e. Unit display mode: INC (▲) key press in measurement mode causes to enter into this mode. In this

mode present measured pressure unit will display at pressure display section. This mode remains

for 5 sec.

Display Indication of each unit is as mentioned below:

mbar ->

mmHg ->

cmH2o ->

Figure: 1

f. Dew point display mode: SHIFT (◄) key press in measurement mode causes to enter into this mode.

In this mode Dew point Value will displays in unit of degC in the place of humidity display

section. This parameter display remains until next ◄ key press or reset of instrument.

8.2. Keys Functionality:

CPM has keypad with five keys named PRG/ESC, SHIFT, INC, DEC, OK/ACK.

Functionality of each key described below:

8.2.1 PRG/ESC Key: This key was used to enter into instrument configuration mode from measurement

mode. And also used for exit from configuration mode and sub modes of configuration mode.

8.2.2 SHIFT Key (◄): This key was used to select the edit digit, while editing the values in

configuration mode. This was also used for enter into the dew point display mode from measurement

mode.

8.2.3 INC Key (▲): This key was used to increment the editing digit value in configuration mode. This

key was used to enter into Unit display mode from measurement mode and also exit from unit display

mode to enter into measurement mode.

8.2.4 DEC Key (▼): This key was used to decrement the editing digit value in configuration mode.

8.2.5 OK/ACK Key: This key was used to accept the edit value in configuration mode. And also used to

acknowledge the process violation, to enter in to measurement mode from violation mode. Hold this

key for 5secs causes to enter into Auto zero calibration mode, while instrument is in measurement

mode.



8.3. Configuration mode:

To enter into this we need to enter valid Entry Code. It will asks code reentry, if

wrong code enters, this for once only. If enter wrong password for second time it automatically comes

out to measurement mode. Default Entry Code is 1111. User can change this in entry code change

mode.

Configuration mode has multiple number of Programming parameters and sub modes to configure,

As stated below:

o Unit selection

o Resolution Selection

o Instrument Calibration

o Set point Range Selection

o Measurement Range Selection

o Sensor Offset Selection

o Config. Sub mode

o Communication parameters sub mode

o Entry Code Change

o Display Section test

8.3.1. How to select mode: Valid password entry causes to display fist programming parameter. Password

reentry is allowed for once only, in case of wrong password entry. To wrap around the parameters

selection, use INC/DEC key. To change the specific parameter, press OK key to accept it. Flow for

one of the parameter or sub mode selection is as shown below.

Press OK key to edit the corresponding programming parameters mode. Then corresponding mode

parameters will display and press ESC key to come out from the mode.

If time out occurs, no key occurs for 30 sec, instrument automatically comes out from

configuration mode and enters into measurement mode.

In the calibration mode this time out is 30 minutes, to stabilize process value.

8.3.2. Individual mode Description: This section describes about how to edit each programming

Parameter mode and brief description about each one.

8.3.2.1 Unit Selection: This mode is to edit the unit of pressure and temperature parameters. When unit

change occurs, set point range, measurement range, sensor off set comes to default values. When ever

unit changes for any process parameter unit, calibration should do again.

Note: When pressure units changes resolution of the parameter automatically changes to specified

value in instrument specifications.

All three process parameters can calibrate individually. In calibration mode, actual value (Direct

value read from sensor) of the process parameter will display to calibrate.

Since the humidity process value is dependent on the temperature process value, do the

temperature calibration before the humidity calibration.

To calibrate process parameter, select YES option when instrument ask for corresponding



parameter. After select YES to calibrate instrument will display “wait”. Until current process value

read from the sensor. To edit the process value press OK key after get stabilized process value and

Mode: RTU mode.

Baud rate: 9600bps (default)

Bits Per Byte: 8-bit

Start bit: 1

Stop bit: 1

Parity: Even

Note: CPM supports variable baud rate. User can change the Baud rate through keypad in

programming mode. Supported baud rates are 9600, 19200, 38400 bps.

9.2. Memory Mapping:

CPM supports three function codes; listed “Read input registers”, “Write single register” and

“Write holding registers”. Each Register is of length 16 Bit. Float values are stored as standard IEEE-



754 floating format. This format occupies 4 bytes.

9.2.1. Input Registers (3X): Input Registers stores process value of the parameters in float and integer format.

Integer value can convert in to float by dividing with resolution of respective parameter.

Appendix:

How to check RS-485 Communication:

1. If the communication LED blinks for every polling then communication is working properly.

2. Even communication LED blinks, if readings from instruments fails then do the following steps.

3. Switch off the power of all the instruments in the network.

4. Disconnect the instrument to be checked from the net work and switch ON the instrument.

5. Check the voltages across +and -, + and G, - and G terminals at the instrument.

6. The voltage across + and - should be greater than or equal to 3.0V

7. Voltage across +and G should be greater than voltage across + and - terminals.

8. Voltage across – and G should be difference of voltage across +/G and +/- terminals.

9. If the steps 4 to 6 are met checked instrument RS-485 section working properly, otherwise remove

the instrument and contact factory.

10. Do the same procedure for all the instruments. If all the instruments RS-485 section is OK, check

the input lines to the CPM105 network.
