Can output alarms by installing L1, L2, L4 or L5 relay output module.
⑦
Shows the module type of communication (COMM):
Installing S or S4 module can communicate with RS485 interface.
⑧
Shows type of power supply:
Null indicates 100
~
240VAC power supply, and “24VDC” indicates 20
~
32VDC/AC power.
Note 1:
4
~
20mA or 0
~
20mA standard current signal can be inputted by converting to 1
~
5V/0
~
5V voltage
signal with a 250 ohm resistor or installing I4, module in MIO slot. I4 can supply 24VDC power to 2-wire
transmitter.
Note 2:
D dimension instruments have no MIO slot, and its COMM and ALM share the same slot and can’t be
installed at the same time. Its ALM only, support AL1 single loop alarm. D2 dimension instruments have
only OUTP slot and COMM / AUX slot.
Note 3:
Current module X3 and RS485 communication module S share the same power supply in the instrument,
and are not electric isolated to each other. Therefore, if X3 current module is installed in OUTP slot and
RS485 communication is need at the same time, then RS485 communication module should be S4
which itself has isolated power supply.
Note 4:
The instrument applies the technology of auto zero and digital calibration, and is free of maintenance. If
the error exceeds certain range, generally, cleaning and drying the inside of the instrument can fix it. If
not, send the instrument back to the factory to examine and repair.
Note 5:
Free repair and maintenance will be given in 36 months since the delivery. In order to get full and correct
repair, write the phenomena and causes of the malfunction of the instrument.
