Typical Installation

The CDCN-44I can be installed in 3 different ways: Panel, 2” Tube and Flat Surface. For installation purpose the instrument is offered with the following hardware: 2 Installation Support, 4 SS screws ¼" x ½", 4 SS washers ¼", 2 "U" SS clamps , 2 SS nuts and 2 SS washers ¼". These hardware allow 3 different ways for installation, to know:

a) Installation in 2” tube: Uses 2 installation support + 2 "U" clamps with nuts and washers. b) Installation in Panel: Uses 2 installation support ; the edges will be placed against the internal

surface of the panel, 4 screws. ¼" x ½” will be used to hold it in place. c) Installation in Flat Surface(Wall Mount): Uses 2 installation support and “U” clamps holes are also used to hold the instrument in place at flat surface.

Electrical Installation

1- Remove the equipment from the box and verify for any possible damage caused during transportation; 2- Install the equipment at an strategic place, allowing easy access, exempt of vibration and vapors, follow the information supplied on page 6 (Typical Installation); 3- Avoid exposing the equipment direct to solar rays; and if necessary supply protection to the case; 4- Verify if the electrical installation is correct, and if security circuit breakers are installed and if grounding is performed correctly; 5- Proceed with the equipment installation.

Electrical Installation

1- Remove the frontal lid of the equipment; 2- Insert the cables thru the cable knockouts, certifying that the connections are correct, verifying the identifications drawing and the electrical schematics; 3- The cables must be firmly attached to the cable knockout, avoiding humidity from being created inside the equipment and preserving IP 67 enclosure;.

Never cut or mend the probe cables, as reading errors could occur.

Set Up Operation

The menus are self explanatory with its respective options, that are selected by press key. When the selected option flashes, press key to confirm the selected option. If a mistake is made, press key to go back (one step at every touch) and modify the option, except while during Reading Mode, when key needs to be held for about 5seconds in order to exit this mode.

The equipment offers a non-volatil memory (E2PROM), in order to store operations functions (resolution, reading, Calibration and more). Even when turned off from power, all functions chosen during set up will remain stored.

Before starting any work with the equipment, it is recommended to to certify that you have chosen the correct options for the operation . When at the , press key in order to select the desired function, flashing option, then press , press key until SET function flashes, then press . A Password will be requested, press in sequence ,

2- key will only be recognized if pressed for a longer period of time (about 5 seconds), while at Reading Mode. This time is necessary in order for the equipment to certify that the user really wants to exit the Reading Mode. 3- In the event of a power failure, the equipment will retain initial set up as prior of being turned off, when the power returns, the outputs and the display will return to activities prior of being turned off. 4- Every time the cell is replaced by a new one, it is necessary to match the thermo compensator value with the instrument and in order to do so, place tap water into a beaker then using a thermometer, measure the Temperature of the tap water (C). Access SET UP Mode and when prompted with question “NEW CELL?” choose YES, then confirm by choosing YES again, then adjust the temperature shown at the display in order to match the temperature of the water at the beaker, then press Enter and wait until finished. When the instrument is shipped from factory with the instrument, the cell had been previously thermostatized and no further procedure is necessary!

Communication Protocol

Communication Protocol:

1) Proprietary:

Order:

ESC ID P CR LF 0x1B 0x50 0x0D 0x0A Hexadecimal

The ID is configured at the instrument from 1 to 32.

Answer:

L > > V V V V V V mS/cm C C C C C C m A

Example of answer for an un-stable value

L > 0. 02 mS/cm 1 2 . 0 0 m A

Example of answer for a stable value

L > > 0 . 02 mS/cm 1 2 . 0 0 m A

Note: a) When the answer comes a C instead of a L, it means that the equipment is under calibration function (is being operated in location by the user, executing the calibration operation at the instrument). b) When the answer comes an S instead of a L, it means that the equipment is under Set Up function and it is being operated in location by the user.

2) RS485 – It is a “physical location”, where the proprietary protocol will be “transported”.

As factory default, this communication comes configured as:

Speed = 9600 Parity = none Number of Bits = 8 Stop Bit = 1 ID = 1
