Thank you for choosing Delta’s DVP series PLC. Delta releases DVP02LC-SL load cell
module of weight measurement function. DVP02LC-SL provides 24-bit resolution
applicable for 4-wire or 6-wire load cells with various eigenvalues. Therefore, the
response time can be adjusted in coordination with each other according to users’ needs.
On this basis, the market requirements on weight measurement can easily be met.
aThis instruction sheet provides introductory information on electrical specifications,
general specifications, installation and wiring.
aThis is an OPEN TYPE I/O module and therefore should be installed in an enclosure
free of airborne dust, humidity, electric shock and vibration. The enclosure should
prevent non-maintenance staff from operating the device (e.g. key or specific tools
are required to open the enclosure) in case danger and damage on the device may
occur.
aDO NOT connect the input AC power supply to any of the I/O terminals; otherwise
serious damage may occur. Check all the wiring again before switching on the power.
Make sure the ground terminal is correctly grounded in order to prevent
electromagnetic interference.
aThe tightening torque for I/O terminal block is 1.95 kg-cm (1.7 in-lbs). Use 60/75°C
copper conductors only.

Steps for correction: Take CH1 for example
1: Place no weights on the load cell
2: Set up CR#26 command = “H’0001”
3: Place standard weights on load cell
4: Write the weight of the weights on the plate
into CR#33.

#35 H1023 OR CH1 max. weight
#36 H1024 OR CH2 max. weight
Set up the max. weight. When the measured
value exceeds the set value, error codes will
be recorded.
#37 H1025 OR/W Upper limit for CH1
zero point check
#38 H1026 OR/W Upper limit for CH2
zero point check
Reference for reset to zero. When the weight
is within this range, the status code will be set
to “zero bit”, indicating the current zero
weight status.
Default: K10
Range: K-32,768 to K32,767
#39 H1027 OR/W Lower limit for CH1
zero point check
#40 H1028 OR/W Lower limit for CH2

#41 H1029 X R/W Saving set value
(H’5678)
Save the present set value and write all the
set values into the internal Flash for use next
time DVP02LC-SL is switched on.
H0: No action, Default
H’FFFF: Saving is successful
H’5678: Write to internal Flash
When H’5678 is written in, all set values will
be saved in Flash. When the saving is
completed, CR#41 will become H’FFFF. If the
value written in is not H’5678, it will
automatically return to H0, e.g. write K1 into
CR# to return to K0.
