This quad channel thermocouple con-

troller is ideal for numerous industrial

temperature applications. It accepts di-

rect sensor input from all common ther-

mocouple types.

One of the key features of this controller

is its ability to average the inputs across

2, 3 or 4 temperature channels, and use

this averaged value for a display source

or for setpoint activation.

5.2 - Display

The data source for the Display determines what will be displayed on the screen

when the controller is in normal operating mode - you can set this in 6.3B.

Most of the available data sources can be selected (see 5.1). You can also select 'AUTO', which will cause the display to cycle continuously through the four

temperature input channels.

While 'Display' has its own data source, it can also be used as a data source - for a

setpoint, the analog output, the serial output, or the peak and valley values. This will

essentially mirror the display data source to the selected output, allowing the cycling 'AUTO' feature to be used with other outputs, if desired.

5.3 - Temp 1 – Temp 4

An individual temperature channel can be used as a data source by selecting TEMP 1, TEMP 2, TEMP 3 or TEMP 4. Individual temperature channels can be used as a data

source for any kind of controller output (see 5.1).

5.4 - Multi channel data sources

For multi channel functions to operate correctly, you must specify how many chan-

nels are to be included in the sample range (see 6.3G: 'Number of Channels for Multi

Channel Functions').

Note that the controller will assign channels sequentially if you select less than 4. I.e. Selecting 2 CH will use channels 1–2; 3 CH will use channels 1–3. 4 CH will use channels 1–4.

A Average Temperature

The Average Temperature (rendered on your LED display as 'AVETMP') is a cal-

culated value, created by averaging 2, 3 or 4 of the thermocouple input chan-

nels, as selected in 'Number of Channels for Multi Channel Functions' (6.3G).

This value can be used as the default view for the operational display, or as a

data source for analog output, serial output, setpoint control, or the peak and valley values. The AVETMP value can also be viewed via the

button on the

main display (see 2.3).

B Max/Min Temperature

Max Temperature (MAXTMP) and Min Temperature (MINTMP) are the maxi-

mum and minimum instantaneous temperatures, taken over the number of

channels selected in 'Number of Channels for Multi Channel Functions' (6.3G).

For example, if you selected 3 CH in 6.3G, then the controller will sample channels 1–3 continually to maintain up-to-date MAXTMP and MINTMP values. If CH1=60.5, CH2=60.8 and CH3=60.6, then the MAXTMP value at that point in time will be 60.8, and the MINTMP value will be 60.5.

The MAXTMP or MINTMP value can be used as the default view for the op-

erational display, or as a data source for analog output, serial output, setpoint

control, or the peak and valley values.

C Multiplexing

The Multiplex (MPX) feature was designed for PLC interface, and allows the

PLC to determine, via the controller's 'Pk/Val' and 'Hold' function pins (see 3.6),

which temperature channel will be used as a data source for the analog output.

To activate this feature, your analog output data source must be set to MPX (see 6.6B). When you activate MPX, the default functions of the 'Pk/Val' and

'Hold' pins will be deactivated, and the pins will be used to determine which

temperature channel is used for the analog output, as shown in the table below.

Channel Pk/Val Hold

TEMP 1

OFF OFF

TEMP 2

ON OFF

TEMP 3

OFF ON

TEMP 4

ON ON

Note that when changing the 'Pk/Val' or 'Hold' pins in MPX mode, you need to

allow a settling time of at least 0.5 seconds before reading the analog output

current.

5.5 - Peak & Valley

Peak and Valley are the maximum and minimum values measured since the instrument was turned on or reset. (These values dier from MAXTMP and MINTMP, in

that they will hold the maximum and minimum values until they are reset.)

The Peak and Valley data source can be set (in 6.3F), to a range of options as shown

in table 5.1.

Peak and Valley can be viewed from the front panel using shortcut keys (see 2.3),

or appear continually on the main display (if you set one of these variables as your

display data source). They can also be reset via the front panel (2.3), the rear pins

(3.6), or by restarting the controller.

While 'Peak' and 'Valley' have their own data source, they can also be used as data

sources - for the display, analog output, serial output, or setpoint control.

INPUT SETUP & CALIBRATION

6.1 - Enter F1 PIN number

A Enter the calibration mode by pressing the button.

_ _ _ ENTER F1 PIN NUMBER scrolls across the display and toggles with 0. Use

the

and buttons to enter your security code (factory default 1). Then

press . If the correct PIN is entered, setup is started at 6.2.

If an incorrect PIN number is entered, _ _ _ INCORRECT PIN – ACCESS DENIED

scrolls across the display and it returns to normal operating mode.

You will have the opportunity to change your PIN number at the end of this section (6.8). If you have forgotten your PIN number, see Section 9.

6.2 - Input setup

A _ _ _ INPUT SETUP scrolls across the display and toggles with SKIP. Press

skip to 6.3, or the button and then to ENTER input setup.

B _ _ _ MAINS FREQUENCY scrolls across the display and toggles with the current

selection. Use the

and buttons to select 50HZ or 60HZ, and press .

C _ _ _ SENSOR TYPE scrolls across the display and toggles with the currently

selected sensor type. Use the

and buttons to select J TYPE, K TYPE, R

TYPE, T TYPE or N TYPE, and then press .

D _ _ _ NUMBER OF SENSORS scrolls across the display and toggles with the

current selection. Use the

and buttons to select how many of the 4 tem-

perature channels are connected. Then press .

Channels are assigned sequentially. I.e. Selecting 2 CH will use channels 1–2; 3 CH will use channels 1–3, etc. See 3.2 for wiring.

E _ _ _ TEMPERATURE SCALE scrolls across the display and toggles with the cur-

rent scale. Use the and buttons to select DEG C (°C) or DEG F (°F), and

then press .

F _ _ _ AVERAGING SAMPLES scrolls across the display and toggles with the cur-

rent averaging. Using the and buttons, alter the number of input samples

that the controller will average, and then press .

This feature allows signal averaging of each individual input channel, to optimise stable measurement. (This is dierent from Multi-Channel Averaging, as explained in 5.4A.)

If the change in input exceeds the averaging window value it will not average, ensuring fast response when there are large dierences between readings.

Increasing the number of AVERAGING SAMPLES will stabilise measurement, but it will also slow down response rates.

Input exceeds averaging window

G _ _ _ AVERAGING WINDOW scrolls across the display and toggles with the cur-

rently selected signal averaging window value. Using the and buttons,

alter the signal averaging window. Then press .

If your input signal contains large noise spikes, you can increase the size of the averaging window to ensure that these are still averaged. However, increasing the window size too far will reduce the ability of the controller to respond quickly to real changes in input signal. Setting AV- ERAGING WINDOW to 0 will give continuous averaging as per the selected averaging samples.

6.3 - Display setup

A _ _ _ DISPLAY SETUP scrolls across the display and toggles with SKIP. Press

to skip to 6.4, or the button and then to ENTER display setup.

B _ _ _ DISPLAY SOURCE scrolls across the display and toggles with the currently

selected display source. Use the

and buttons to choose between: AUTO,

TEMP 1, TEMP 2, TEMP 3, TEMP 4, AVETMP, MAXTMP, MINTMP, PEAK, or VALLEY. Then press .

¨ If you selected AUTO, continue to 6.3C now.

¨ If you selected something else, skip to 6.3D now.

Note that your options in this step will be limited by the 'Number of Sensors' selected in 6.2D. For more information about display data sources, see 5.2.

In Auto mode, the main display constantly cycles through all available input channels (I.e. TEMP 1, followed by the current value for that channel, then TEMP 2, TEMP 3 etc).

C _ _ _ DISPLAY TIME IN SECONDS scrolls across and toggles with the current

selection. This setting is only used for AUTO display (see 6.3B), and is the pause

time between variables as they cycle on the display. Use the and buttons

to adjust this value as required, and then press .

D _ _ _ UNITS scrolls across the display and toggles with the current setting. Use

the

and buttons to select either YES or NO, and then press .

E _ _ _ RESOLUTION scrolls across the display and toggles with the currently se-

lected resolution. Use the

and buttons to choose between 1DEG and 0.1,

and then press

currently selected peak and valley source. Use the

and buttons to select:

DISP, TEMP 1, TEMP 2, TEMP 3, TEMP 4, AVETMP, MAXTMP or MINTMP, and

then press .

Note that your options in this step will be limited by the 'Number of Sensors' selected in 6.2D. Additionally, if your display source (6.3B) is set to either 'PEAK' or 'VALLEY', then 'DISP' will not appear as an option, as this would create a circular reference.

For more information about Peak/Valley data sources, see 5.5.

G _ _ _ NUMBER OF CHANNELS FOR MULTI CHANNEL FUNCTIONS scrolls

across and toggles with the number of channels to be included in multi channel calculations, including the AVETMP, MINTMP and MAXTMP values. Use the and buttons to select: NONE, 2 CH, 3 CH or 4 CH, and then press .

Note that your options in this step will be limited by the 'Number of Sensors' selected in 6.2D. For more information about multi-channel data sources, see 5.4.

A _ _ _ CALIBRATE scrolls across the display and toggles with SKIP. Press

now

to skip to 6.6, or use the and buttons to select a channel to calibrate (TEMP 1, TEMP 2, TEMP 3 or TEMP 4), and then press .

The number of channels available for calibration are determined in 6.2D (Number of Sensors).

B _ _ _ APPLY LOW TEMPERATURE – – – –ENTER LOW DISPLAY VALUE scrolls

across the display, and the currently selected low display value appears. Apply

the required low level temperature to the meter, and wait a moment for the

signal to stabilise. Then use the and buttons to set the required low level

display value, and press to accept.

C _ _ _ APPLY HIGH TEMPERATURE – – – –ENTER HIGH DISPLAY VALUE scrolls

across the display, and the currently selected high display value appears. Apply

the required high level temperature to the meter, and wait a moment for the

bled setpoint will exit and return to the operational display.

RESET PIN NUMBERS / VIEW FIRMWARE VERSION

If you have forgotten your PIN number(s), follow the procedure below to reset both the F1 and F2 PINs to their factory default of 1.

This procedure will also allow you to view the current soware installed on your controller, which may be required for support purposes.

A Press

, and at the same time. (This key combination can be dicult to

execute and you may need several tries to get it right.)

B A message will appear on the display, with details of the unit's current soware

conguration (Product Name, Firmware Version, and Macro Version). At the end, you will see – ALL PIN NUMBERS RESET TO 1.

and 7.3, entering ‘1’ whenever you are prompted for your current PIN.

APPENDIX A - SERIAL MODES

A.1 - Custom ASCII mode

Custom ASCII is a simple, custom protocol that allows connection to various PC con-

guration tools. ('Custom ASCII' diers from the 'Modbus (ASCII)' protocol used by

some devices.) Custom ASCII command strings must be constructed in this order:

Start - Use 'S' for the start character of a command string (not case sensitive). This

must be the rst character in the string.

Controller Address - Use an ASCII number from '1' to '255' for the controller address.

If the character following the start character is not an ASCII number, then address '0' is assumed. All controllers respond to address '0'.

Read/Write Command - Use ASCII 'R' for read, 'U' for unformatted read, or 'W' for

write (not case sensitive). Any other character aborts the operation.

In Custom ASCII mode, data is normally read as formatted data (which includes decimals and any text characters that may be selected to show units). However it is also possible to read unformatted data by using a 'U' in the read command. There is no unformatted write command, as when writing to xed point registers, any decimal point and text characters are ignored.

number from '1' to '65535'. This character must be specied for a write com-

mand, but may be omitted for a read command, (in which case the controller

will respond with the data value currently on the display).

Separator Character - The separator character can be either a space or a comma,

and is used to separate the register address from the data value.

Data Value - Must be an ASCII number. The absolute limits for this number are

–

1000000 to +1000000, but note that not all registers will accept this range.

Message Terminator - This is the last character, and must be either a '$' (dollar) or

an '*' (asterisk). Neither of these characters should be used elsewhere in the

message string. If '$' is used, a 50ms minimum delay is inserted before a reply is sent. If '*' is used, a 2ms minimum delay is inserted before a reply is sent.

Custom ASCII Read/Write Examples

Example Description

SR$ Read display value from all controllers, 50ms delay.

S15R$ Read display value from controller address 15, 50ms delay.

S3U40* Read unformatted data in channel 4 from controller address 3, 2ms delay.

S2W2 –10000$ Write

–

10000 to the display register of controller address 2, 50ms delay.

SWT CHAN_1$ Write ASCII text string Chan_1 to channel 1 text register, 50ms delay.

Controller Response - Aer the controller has completed a read or write instruction,

it responds by sending a carriage return/line feed (CR/LF) back to the host. If

the instruction was a read command, the CR/LF follows the last character in the

ASCII string. If it was a write command, CR/LF is the only response sent back.

The host must wait for this before sending further commands to the controller.

If the controller encounters an error, it will respond with a null (0x00) CR/LF.

A.2 - Modbus (RTU) mode

Modbus (RTU) is an industry standard RTU slave mode that allows connection to a

wide range of devices. Modbus registers are all holding registers, and should be ac-

cessed via function codes 3 and 6.

Note: Address 416543 is a read/write null terminated text string, into which you can write your own identication text (up to 62 characters). This is accessed using a standard Modbus read/write command for holding registers, where each 16 bit register holds 2 x ASCII string characters in sequence.

A.3 - Ranger A mode

Ranger A is a continuous output, used to drive remote displays and other instru-

ments in the Rinstrum™ range. (Ranger is a trade name belonging to Rinstrum Pty

Ltd.) Ranger A output strings are constructed as shown:

Start - STX character (ASCII 02)

Sign - Output value sign (space for + and dash for -)

Output Value - Seven character ASCII string containing the current output value and

decimal point. (If there is no decimal point, then the rst character is a space.

Leading zero blanking applies.)

Status - Single character output value status. 'U'=Under, 'O'=Over, 'E'=Error.

End - ETX character (ASCII 03)
