mA.
Using mA is possible to control the status of “mA outputs” based on some parameters. Refer to “I/O connections”
blocks at page 5 to locate these outputs over the mainboard. Once that mA1 function is enabled (move wheel over
“disable” , press, rotate to “enable”, press again to exit) then main parameters are
OUTmA, LEV, STOP and pH - mA.
Out: is referred to “mA outputs” from “I/O Connections” of mainboard. Set this value between available outputs. If an
output is already used then it’ll be hided from list.
IN: assign “input” number then edit the name by moving wheel. If the “input” number is already used then it will not be
shown. Choose “X” instead of a number to disable input.
STOP: (“ON”: when product into tank is ending, then the related output will be off and an alarm condition will pop-up.
“OFF”: when product into tank is ending, then the related output will continue to stay on and an alarm condition will pop-up.)
MSG: when agged an SMS or EMAIL alarm message will be sent to destination edited in GSM menu.
pH - mA
These elds require to set two pH values with mA for a proportional working mode. This mode let the instrument to
modulate mA proportionally to reaching value. mA range is from 0 to 20mA.
For example: Set rst pH to 10.00 with 15mA. Set second pH to 7.00 with 0mA.
If reading value is 10.00 then 15mA will be forwarded to related output.
If reading value is 7.00 then no mA will be forwarded to related output.
If reading values are 8.5 then 7.5mA will be forwarded to related output.
Note: for 2 CD channels and 5 4/20mA outputs version the setpoint on Ch. 2 operates for all mA outputs
