2.2 Mounting the Recorder on the Wall
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):
M4098-F2-4a.eps
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.

2.3.2 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.
NOTE
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.

2.5 Installing and Removing Pens
The recorder already comes with the two pens installed. While the unit is turned
off, open the recorder door and remove the pen caps from the two pens. Place
the pen caps in a secure location for reuse.
2.5.1 Installing the Pens
The recorder uses two different colored pens to record information. The
red (upper) pen records temperature. The blue (lower) pen records relative
humidity. Pen life varies with use and climate. Under normal operating
M4098-F2-9
conditions, pens last at least one month. We recommend that you install a fresh
set of pens after every month of use.
To install pens:
1.Make sure the recorder is turned off. The recorder door should be closed.
2. Examine the location of the pen arms through the window in the recorder door.

The
real time clock
has its own rechargeable battery back up. The clock continues to operate when the
main power is removed for about 14 days. There is no need to change the real time
clock battery since it gets charged every time the main power is present.
The recorder has two built-in Relays and provides an additional two voltage
outputs to drive external mechanical relays. There is a 10 position terminal block
in the back of the recorder. It provides the two relay contact closures & two
signal outputs to drive external mechanical relays as shown in Fig 2.14. In order
to do your wiring, remove the terminal block from the back of the recorder.
Connect your wiring, then plug the terminal block back in its place.

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.
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.

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

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

In order to calibrate the input channels, you need to enter the password “calph”.
Then you can calibrate each input channel. At every calibration point, you
need to simulate either the pH millivolt signal equivalent or RTD resistance
equivalent.
pH Calibration:
Simulate 4 pH = +177.5 mV , then Press ‘Set Low’
Simulate 7 pH = 0 mV , then press ‘Set High’
RTD Temp Calibration:
Simulate 100 ohms RTD @ 20 ºC = 107.8 ohms , then press ‘Set Low’
Simulate 100 ohms RTD @ 80 ºC = 130.9 ohms , then press ‘Set High’
Then press ‘Save’ to complete the calibration process.

Wireless Temperature/Humidity

WIRELESS
RECEIVER
WIRELESS
TRANSMITTER
8.1 Introduction
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.

Dimensions, Labels and descriptions.
Figure 8-2 shows the Battery location in the wireless transmitter. You need to

8.2 Configuration
The wireless transmitter and receiver have the following factory default
configuration:
Transmission time interval: 2 seconds
Channel Frequency: 915 MHz (US & Canada) or 868 MHz (Europe)
Unit ID: 00 (Both transmitter & receiver)
The user does not have to do any configuration to the transmitter or the receiver
if the factory configuration is satisfactory. However, if the user wants to change
the configuration, then you need to run the configuration software that comes
with the unit. Through the configuration software, the user can change the
transmission interval, channel frequency and the unit ID number. First install the
configuration software on your PC.
Configuring the wireless Transmitter – Turn off the battery power. Connect
the transmitter to the USB port of the PC with the cable provided. Run the
configuration software. Figure 8-8 shows the main menu of the software. The
buttons and the menu selections are described as follows:
Run – It will display the temperature/humidity in real time.
Program – It will save the new settings to the transmitter.
Read – It will read the current settings of the transmitter

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:
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.

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.
