PT200MI instruction manual 34
10.7 SINGLE MATERIAL BATCHING CONTROL SOFTWARE OPTION
This function will NOT be available if the software option has not been ordered.
This function requires a comparator option card to be fitted. Refer to the comparator option section for
connection details
This function requires factory configuration and must be ordered at time of indicator purchase.
10.7.1 KEYPAD SETTING STEPS
Enter the single material batching setting mode: Press and hold MODE , then press the ZERO key, 2
seconds later the PT200MI displays “SET”, a further 2 seconds later the gross annunciator begins
flashing and the PT200MI displays “000000”
Step 1: Final set-point setting
The display value is the final batch weight. Select the digit to change by pressing the ZERO key and
set the value by pressing the TARE key. During this step the gross annunciator flashes.
Accept the data by pressing the MODE key.
Step 2: Optional preliminary setting (OP or HH output)
The display value is the optional preliminary weight. This is the weight before the final set point at
which the OP output will switch. Select the digit to change by pressing the ZERO key and set the
value by pressing the TARE key. During this step the net annunciator flashes.
Accept the data by pressing the MODE key.
Step 3: Preliminary setting (PL or HI output)
The display value is the preliminary weight. This is the weight before the final set point at which the PL
output will switch. Select the digit to change by pressing the ZERO key and set the value by
pressing the TARE key. During this step the motion annunciator flashes.
Accept the data by pressing the MODE key.
Step 4: Free fall setting (FF or LO output)
The display value is the free fall weight. This is the weight of material already in motion that would fall
into the hopper after the inflow is stopped. Select the digit to change by pressing the ZERO key
and set the value by pressing the TARE key. During this step the zero annunciator flashes.
Accept the data by pressing the MODE key.
Step 5: Zero band setting (ZB or LL output)
The display value is the zero band weight. This is the weight below which the hopper is considered to
be empty. Select the digit to change by pressing the ZERO key and set the value by pressing the
TARE key. During this step the kg annunciator flashes.
Accept the data by pressing the MODE key.
Step 6: Exit single material batching setup
Press MODE key to return to the normal weighing mode.
An error occurs if correct setting conditions are not satisfied
Final setpoint > Optional preliminary > Preliminary > Free fall. (> means greater than)
In this event press MODE key to restart from step 1 to step 5.
The logic table below defines the output states. Net value is the net indicator weight.
Condition
OP(HH) PL(HI) FF(LO) ZB(LL)
Net value <= Zero band ON OFF OFF ON
Net value > Zero band and Net value < Optional preliminary OFF OFF OFF OFF
Net value >= Optional preliminary and Net value < (Final – Preliminary) ON OFF OFF OFF
Net value >= (Final – Preliminary) and Net value < (Final – Free fall) ON ON OFF OFF
Net value >= (Final – Free fall) ON ON ON OFF
10.7.2 RS232/RS485 SETTING STEPS. (An RS232 or RS485 option must be installed)
Set-point setting can be conveniently performed by using RS232/RS485 during normal weighing mode.
Refer to the section on RS232/RS485 for connection diagrams.
From the RS232 port, input a command “SET<CR><LF>”, “CAL 1<CR><LF>”, the display will show
“SET” throughout the calibration setting mode.
