M4098-F2-4b.eps

To mount the recorder on the wall, first locate the wall mounting holes using the template provided in the wall mounting kit. Leave the decorative foot cover (Figure 1-1, item #18) in place*. After drilling the holes, insert the wall anchors and put in the screws, leaving 1⁄8 inch (3 mm) between the screw heads and the wall. Hang the recorder by positioning the two (2) “keyholes” in the rear cover over the screw heads.

* If the decorative foot cover is not in place, go through the following steps to

reinstall the cover (if desired):

1. Place the recorder on the table (so it is front face up).

2. Roughly position the foot cover so the clips are in line with the stabilizing

arm. Gently “stretch” the clips out and position over the arm as shown in Figure 2-4a.

3. Once the clips are in place, gently slide down until the foot cover is even

with the front of the recorder as shown in Figure 2-4b.

2.3 Using Batteries

The recorder operates on either four “D” size non-rechargeable alkaline batteries or a universal (100-240 Vac, 50-60 Hz) ac adapter.

2.3.1 Installing Batteries

You may power the recorder with four “D” size alkaline batteries. Under normal conditions, the recorder operates full time on battery power for up to three months when using fresh alkaline batteries. When replacing batteries, we recommend that you use Alkaline “D” size batteries for long life and for best performance at low temperatures.

To install the batteries (refer to Figure 2-5):

NOTE

In the event of ac power failure, the unit will switch over to battery power automatically. Keep a fresh set of batteries in the unit in case of power outage.

2.3.2 Connecting ac Power

The recorder can be ac powered using the universal 100-240 Vac adapter supplied. The dc power jack is located on the right side of the unit (refer to Figure 1-1, item #6.). The ac adapter provides 9 Vdc @ 1.7A power output and comes with a 1.8 meters (6 ft.) long cable.

The following parameters are stored in the non-volatile memory and will not be lost when batteries or main power are removed

• Chart speed & scale

• High & low alarm set points for the two channel

• Chart Data points

When the recorder runs only on AC adaptor, and the main power restores after a power failure, the recorder turns on automatically without pressing the Power Key. All LCD segments turn on momentarily, then there is a 20 second delay before the revision screen. This only happens when the power is removed without pressing the Power Key. The pens go to the home position and back to the correct chart scale everytime the recorder powers up.

2.10 Open/Out of Range Input

If the input to the recorder is open or out of range, the chart motor continues to run but the recorder handles the situation as follows:

1. Temperature/Humidity Model: When the sensor probe is disconnected, the

pens go to the home position and the display shows “Prb Err”. When the probe is out of range, the display flashes.

2. Dual Thermocouple Model: When any of the two thermocouple inputs open

up, the pens go to the home position, and the display shows “Prb Err”. When the input is out of range, the display flashes.

3. Dual Process input Model: When the two inputs are out of range, the display

flashes.

2.11 Pen Jamming

Each pen drive mechanism has two optical sensors. One is to detect the home position, the other is to detect pen movement. If the pen drive mechanism skips steps due to wear & tear or dirt & dust over a period of time, the recorder can compensate for it so that the pens are at the right location on the chart. If the pens have too much friction or get jammed for any reason, the recorder detects the situation. It turns off both the pen and the chart motors. It continues to display the parameters on the LCD and stores data in the memory. The Chart icon starts to flash to indicate Pen Jamming.

Setting Up the Recorder

Once the pen drive mechanisms are serviced, and the recorder is powered back on, the unit continues to operate normally and the chart icon flashing will disappear.

2.12 Pen Re-scaling

Each or both pens can be re-scaled within the range of the input sensor. Here are the standard chart ranges for the three models:

Temperature/ Humidity Model -17.7 to 49ºC (0 to 120ºF) 0 to 100% RH

Dual Thermocouple Input

Type K -40 to 560ºC (-40 to 1040ºF)

Type J -40 to 260ºC (-40 to 500ºF)

Type T -40 to 160ºC (-40 to 320ºF)

Dual Process Input 0 to 100%

The pens can be re-scaled thru RS232 from the PC using certain commands. See Chapter 3 for more details. Once the pens are re-scaled, the Chart icon turns on. The unit remembers the new pen scales even if the main power is removed. The chart icon will disappear if the pens are scaled back to factory settings.

2.15 pH & RTD Input Chart Recorder

Model CTXL-pH takes pH probe and RTD sensor directly. The pH probe can be connected directly to the recorder via a BNC connector. The RTD sensor from the pH probe can be connected to the terminal block below the BNC connector.

The recorder measures the pH and RTD temperature inputs. It compensates the pH input for the RTD temperature. If the pH probe does not include an RTD sensor, you need to add a 110 ohms resistor (included with the recorder) across the terminal block. This will set the temperature input to a fixed value (about 26ºC).

LIGHT

pH Input Calibration Procedure

The pH input is calibrated at 4 & 7 pH values. From the Hyper terminal, you can use the following PC commands to calibrate the pH input:

I1L<CR> Channel 1, Calibrate @ 4 pH @ 25ºC Buffer (+177.5 mV) I1U<CR> Channel 1, Calibrate @ 7 pH @ 25ºC Buffer (0 mV) I1C<CR> Save pH Calibration

RTD Temperature Input Calibration Procedure

The RTD input is calibrated at 20 & 80ºC values. From the Hyper terminal, you can use the following PC commands to calibrate the RTD input:

I2L<CR> Channel 2, Calibrate @ 20ºC (RTD = 107.8 ohms) I2U<CR> Channel 2, Calibrate @ 80ºC (RTD = 130.9 ohms) I2C<CR> Save Temperature Calibration

pH Offset Adjustment Procedure

pH sensors will deteriorate and drift over time. You can introduce an offset to the pH channel to compensate for this drift. From the Hyper terminal, you can use the following PC commands to introduce pH offset: OF5<CR> Introduce +0.05 pH offset OF125<CR> Introduce +1.25 pH offset OF-7<CR> Introduce -0.07 pH offset OF-175<CR> Introduce -1.75 pH offset OFD<CR> Resets the pH offset back to Zero OFC<CR> Displays the current pH offset value, for example: 0020 means +0.20 pH

3 PC Communication

You can communicate with the CTXL recorder thru RS232 port from a PC. There are a number of PC commands that allows the user to do the following functions:

• Get the data (Like Temperature & Relative Humidity) in real time. This is the

same data displayed on the LCD.

• Download the stored chart data from the recorder to the PC. It will save the

data into a data file. It can then be imported into the Excel spread sheet program for further review and analysis.

• Re-scale the Chart paper for one or both Pens to any range within the input

operating range.

• Reset the Chart scale back to the Factory standard scales.

You can initiate the PC commands from the Hyper terminal or can develop your own program and incorporate these commands. Here are the steps to work from the Hyper terminal:

• From Start Programs Accessories Hyper Terminal

• Create a name for your communication

• Set the communication settings as follows (In the Properties Menu):

- COM port (1, 2, 3)

- Baud Rate (9600)

- Data Bits (8)

- Parity (None)

- Stop Bit (1)

- Flow Control (None)

3.1 Get Display Data in Real Time

You can get the data for channels 1 & 2 in real time. It will be the same data displayed on the LCD. The following two commands perform such functions.

In the Temperature/Humidity Model, the temperature data is multiplied by 10 using the AT command.

Please note that all the PC commands terminate with a Carriage Return. In the Example section of the following tables, the PC commands are in Bold, and the response is in regular text.

Command Description Example

AT Get display data from Chan 1 (Temperature) AT;0748

AH Get display data from Chan 2 (Humidity) AH;0048

3.2 Re-scaling One or Both Pens on Chart Paper

You can re-scale one or both pens to any range within the operating input range. Here are the commands:

NOTE

The rescaling of the Temperature Pen is based on Degree F scale on both CTXL-TRH and CTXL-DTC Models.

Command Description Example

PUT Change Chan 1 Pen (Temp) PUT90; Pen Scale set top chart value

PUB Change Chan 1 Pen (Temp) PUB50; Pen Scale set bottom chart value

PLT Change Chan 2 Pen (Humidity) PLT80; Pen Scale set top chart value

PLB Change Chan 2 Pen (Humidity) PLB40; Pen Scale set bottom chart value

PR0 Issue the new Pen scales values PR0; Rescaled to the recorder

PS Get the Pen scales for PS;0090,0050,0080,0040 Chan 1 & 2

PR1 Re-scale the Pens to the PR1; Rescaled standard Factory scales

In the above example, we are re-scaling both Pens as follows:

Temperature Pen: 50 to 90ºF (Standard: 0 to 120ºF)

Humidity Pen: 40 to 80% RH (Standard: 0 to 100%RH)

After issuing the PR0 command, the new Pen scale values will take affect, otherwise the previous scale values will remain. The Chart icon comes on to indicate new chart scale. The new scale is stored in the non-volatile memory. To restore the Pen scales back to the Factory settings, you need to issue the PR1 command.

The rescaling value can be a negative number on model CTXL-DTC. For example, you can issue a PC command: PUB-100 meaning the bottom of chart for channel 1 starts at -100.

3.4 Humidity Probe Calibration Procedure (CTXL-TRH)

This is a two point humidity calibration, 33% RH and 75% RH. The temperature does not require calibration although it can be certified at room or any other temperature within its operating range. Before the humidity calibration, you must record the humidity reading of the probe at 33% RH & 75% RH environments. If the reading accuracy at these two points are within +/-3% RH, no calibration is required. Otherwise the probe needs calibration as described below:

Example: The probe humidity reading at 33% RH is 37% RH and at 75% RH is 72% RH.

(PC commands are in Bold)

1. Connect the CTXL recorder to a PC with the RS232 cable provided.

2. Run HyperTerminal program from the PC. The COM port setting are: Baud rate: 9600 Data Bits: 8 Parity: None Stop Bit: 1

3. Turn on the power to the CTXL. The probe does not have to be at any specific

humidity environment (Regular room environment).

4. Type HH then press Enter key from the Hyper Terminal. The following

message shows the previous two calibration data (Factory Default setting are 33% RH and 75% RH) saved in the CTXL memory. HH; Humidity calibration saved data are: 00033 00075

5. Type HC then press Enter key to start the humidity calibration, and the

following message will appear. HC; Humidity calibration begins, Please type HUL followed by the measurement value at 33% RH.

6. Type HUL37 then press Enter key. (37 is the value that the probe was reading

at 33% RH humidity), and the following message will appear: HUL37; 00037 Please type HUH followed by the measurement value at 75% RH.

7. Type HUH72 then press Enter key. (72 is the value that the probe was reading at 75% RH humidity), and the following message will appear: HUH72; 00072 Humidity calibration is done. 00037 00072

8. Now the humidity calibration is complete and the probe reading should be in

specs.

Wireless Temperature/Humidity

8.1 Introduction

Chart Recorder

WIRELESS RECEIVER

WIRELESS

TRANSMITTER

This is our standard CTXL-TRH recorder, except that the temperature/humidity probe is wireless. The wireless probe consists of a temperature/humidity wireless transmitter and a wireless receiver.

The wireless transmitter has a built-in temperature/humidity sensor that measures the air quality (Temperature & Humidity). It then transmits the data to a wireless receiver thru an RF link. The transmitter is operated from one AA size lithium battery and/or a DC adapter input. The transmitter also has two LED indicators. One Green LED is for transmission indication. One Red LED is for low battery indication as well as other wireless communication errors.

The wireless receiver plugs directly to the circular chart recorder where a temperature/humidity probe is normally plugged into. The wireless receiver acts as a probe, so the wireless RF link is totally transparent to the circular chart recorder. The recorder thinks that it is directly connected to the probe. This design allows us to offer the wireless probe as an option to all existing recorders in the field. There is no internal upgrade required to make a standard circular chart recorder wireless.

8.4 Error Codes

Transmitter Error Codes

The wireless transmitter uses the Red LED to provide different error information to the user and to the wireless receiver as follows:

Wireless Temperature/Humidity Chart Recorder

bit, No Parity

round DIN connector

2 Red LED Blinks means there is an RF communication error such as Framing, CRC, buffer overflow, etc.

3 Red LED Blinks means that the transmitter fails to communicate with the sensor probe

4 Red LED Blinks means Low Battery indication.

The highest priority error code is 2 blinks for RF communication error. The lowest priority error code is 4 blinks to indicate low battery. If multiple errors occur at the same time such as bad sensor probe and low battery, the transmitter’s red LED will blink 3 times. Only when this error clears, then the transmitter’s red LED will blink 4 times to indicate the low battery.

The red LED error reporting occurs every 30 seconds regardless of the transmission time interval.

Receiver Error Codes

The wireless receiver basically reflects all the error codes of the wireless transmitter as follows:

1 Red LED Blink means No good message has been received from the transmitter within 4 transmission time intervals (like 4 minutes for 1 minute time interval), or 30 seconds minimum. The receiver will continue to search for the transmitter’s message 10 more minutes before deciding that the transmitter is either off, out of order, or out of range at which point the receiver will shut itself off to conserve power.

If the wireless transmitter is back on line after 10 minutes, then the user needs to un-plug the receiver from the recorder and plug it back in to reset the wireless receiver.

8-9

Wireless Temperature/Humidity Chart Recorder

2 Red LED Blinks means there is an RF communication error such as Framing, CRC, buffer overflow, etc.

3 Red LED Blinks means that the transmitter fails to communicate with the sensor probe

4 Red LED Blinks means the transmitter’s Battery is low.

The highest priority error code is 1 LED blink for No good message from the transmitter. The lowest priority error code is 4 LED blinks to indicate transmitter’s low battery. If multiple errors occur at the same time such as bad sensor probe and low battery, then the receiver’s red LED will blink 3 times. Only when this error clears at the transmitter, the receiver will then blink 4 times to indicate the next error, if any.

The red LED error reporting occurs every 10 seconds regardless of the transmission time interval.

Any error code except for the low battery means Probe Error for the chart recorder.
