This quad channel process controller is

ideal for numerous industrial applica-

tions with 0–20mA or 4–20mA DC in-

puts. It can be used either on its own, or

inconjunction with another instrument

(such as a transmitter).

One of the key features of this control-

ler is its ability to average the inputs

across 2, 3 or 4 input channels, and use

this averaged value for a display source

or for setpoint activation.

There is also the option to log your data

and store it in the controller's internal

memory, where it can be printed or re-

trieved in Excel-compatible format for

easy analysis.

that the controller will average, and then press

Page 11

This feature allows signal averaging of each individual input channel, to optimise stable measurement. (This is di erent from Multi-Channel Averaging, which is set up in 5.3I.)

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.

E _ _ _ 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.

F _ _ _ AVERAGING SETUP scrolls across the display and toggles with SKIP. You

are now back at 5.2C. To set up avarating for another input channel, proceeds through steps 5.2C–F again. To continue to 5.3, select SKIP and then press

DISP will use the current display source (selected in 5.3B) for the peak/valley display. (If your display source [5.3B] is set to either 'PEAK' or 'VALLEY', then 'DISP' will not appear as an op- tion, as this would create a circular reference.) CH AVE will use the channel average value.

Peak and valley can be viewed or reset via the main display using the front panel shortcuts (see

2.3), or reset via the rear pins (see 3.6).

I _ _ _ SELECT NUMBER OF CHANNELS FOR AVERAGE DISPLAY scrolls across

and toggles with the number of channels to be averaged to produce the CH AVE value. Use

and to select: NONE, 2 CH, 3 CH or 4 CH, and press .

CH AVE is an internally calculated value which is created by averaging 2, 3 or 4 of the input channels, as selected above. The CH AVE value is stored by the controller and can be used as the default view for the operational display, or as a source for analog output, serial output or

Page 13

setpoint control. The controller will always select channels in sequential order, starting from 1. (I.e. 2 CH will average channels 1 & 2. 3 CH will average channels 1, 2 & 3. 4 CH will average all 4 channels. Any other combination of channels is not possible.)

toggle with the current value for that setpoint. Using the

and buttons,

adjust the selected value. Then press

to accept and continue.

C The name of the next access-enabled setpoint will appear on the display, along

with its setpoint value. Repeat step 7B. The direct access menu will proceed

through all access-enabled setpoints in this fashion. Pressing

for the last ena-

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 Cal and SP 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.

C Reset the default PIN numbers if required by following the instructions in 5.9

and 6.3, 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

Page 24

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

Page 25

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-

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)
