5.2 - How to remove the input module

A If the meter is already installed, remove it from the panel, and unplug all plugs

from the back of the unit.

B Using a small screwdriver or similar implement,

press downward into one of the slots at the

rear of the case. This will disengage one of

the tabs which holds the back plate on, al-

lowing it to be gently levered away at

one corner.

C Holding the loosened corner open

with one hand, disengage the le-

ver on the opposite slot (Fig 1).

D You should now be able to remove the back plate. If it does not unclip easily,

you may need to disengage the two remaining tabs by repeating steps 5.2B–C

on the other side of the meter.

Fig 1

E Slide the analog input module out

of the meter case (Fig 2). (See 3.1D

to identify the input module.)

F Position the headers on the input

module as required for your sensor

type, referring to 5.1.

G Slide the input module back into

Fig 2

the meter case.

Make sure that it is sitting in the tracks on the le and right. Press rmly until the input module is fully inserted and sits ush with the other boards that are visible from the back of the meter.

H Replace the back plate.

Begin by inserting the two lower tabs into the slots, and then position the upper tabs so that they will not catch on the top lip of the meter case. Apply rm pressure until the back plate clicks into place.

I Reconnect the plugs and return the meter to the panel installation.

The HYSTERESIS VALUE denes the separation band between setpoint activation and deac- tivation, and will operate as per the HYSTERESIS TYPE setting selected in 7.3E.

G _ _ _ MAKE DELAY scrolls across the display and toggles with the current delay

value for the selected setpoint. Use the and buttons to adjust the delay

value (in tenths of a second) as required, and then press .

This value denes the time delay between setpoint activation, and when the relay turns on. The time is 1/10’th second resolution.

H The step that you proceed to now will depend on what you selected as your

setpoint source in 7.3B.

¨ If you selected FLOW, TOTAL1, or BATCH, skip to 7.3K now. ¨ If you selected TOTAL2, continue to 7.3I now.

I _ _ _ VOLUMETRIC PULSE scrolls across the display and toggles with the current

selection. Use the

and buttons to select OFF or ON, and then press .

¨ If you selected OFF, skip to 7.3K now. ¨ If you selected ON, continue to 7.3J now.

This function outputs a pulse on the relay when Total 2 ≥ Setpoint Value. This will activate the selected relay for a specied length of time (see 7.3J), which can be adjusted in 0.1 second increments to suit the requirements of externally connected devices. This function is useful for feeding volume information to other equipment.

When the selected setpoint is activated in volumetric pulse mode, Total 2 will reset using the calculation: Total = Total – Setpoint Value, and then resume totalizing.

J _ _ _ PULSE TIME scrolls across the display and toggles with the current selec-

tion. Use the and buttons to select your pulse time (from 0.1 to 10.0

seconds), and then press .

Pulse reset requires a minimum of 0.1 seconds. A combination of high input rates and low setpoint values may exceed this limitation, resulting in missed output pulses.

K _ _ _ OPEN ACCESS TO SP VALUE scrolls across the display and toggles with

the current direct access permission setting for the selected setpoint. Use the and to select either YES or NO, and then press .

When enabled, this option allows the selected setpoint's value to be edited directly aer pressing the button, without needing to enter a PIN number or go through all of the other options. Each setpoint can individually have this option enabled or disabled. See Section 8.

L The step that you proceed to now will depend on which setpoint you are editing.

¨ If you are currently editing SP 1, skip to 7.3N now. ¨ If you currently editing SP 2–6, continue to 7.3M now.

M _ _ _ TRAIL SP 1 scrolls across the display and toggles with the current trailing

setting for the selected setpoint. Use the

and buttons to select OFF or

ON, and press .

If you choose ON, the selected setpoint will track the setpoint value of SP 1, with the setpoint value of the tracking setpoint becoming an oset value.

N _ _ _ EDIT SETPOINT scrolls across the display and toggles with SKIP. You are

now back at 7.3A. To edit another setpoint, follow the instructions from 7.3A–N

again. If you do not wish to edit another setpoint, press now to skip to 7.4.

7.4 - Edit F2 PIN number

A _ _ _ EDIT F2 PIN NUMBER? scrolls across the display and toggles with SKIP.

Press to skip and return to the operational display, or the button and then to ENTER and change your PIN number.

B _ _ _ ENTER NEW F2 PIN NUMBER scrolls across the display and toggles with

the current PIN (default 1). Using the

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 please 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.

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)
