Temperature Controller

This quad channel RTD controller is ideal

for numerous industrial temperature ap-

plications. It accepts direct sensor input

from RTD 385, 392 and CU10 tempera-

ture probes.

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 RTD input channels, as se-

lected 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

main display (see 2.3).

button on the

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

TEMP 2

TEMP 3

TEMP 4

OFF OFF

ON OFF

OFF ON

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.

Sampling

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.

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.

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

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

10000 to the display register of controller address 2, 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.

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)
