1. Panel meter M60-LC
Panel meter for load cells, size 96 x 48 mm (1/8 DIN)
Digital panel meter, with 96 x 48 mm (1/8 DIN) size and 6
digits with 14 mm digit height, for load cell signals. Pro -
vides excitation voltage configurable to +5 Vdc or +10 Vdc
to power up to 8 standard 350 Ohms cells. Scalable read -
ing from 999999 to -199999 with configurable decimal
point.
Tare function, with configurable controls, and ‘auto-tare’
function for automatic tare correction when weight is re -
moved from the cell. Three working modes with different
acquisition speeds and noise rejection to 50 and 60 Hz.
Output and control options with 1, 2 and 3 relays, isolated
analog outputs, Modbus RTU communications, transistor
outputs, SSR control outputs, RS-485 ASCII and RS-232.
Special options up to 4 and 6 relays.
Independent alarms configurable as maximum or mini
-
mum, with activation at setpoint or when reading is
stable, with 1 or 2 setpoints per alarm, hysteresis, inde -
pendent activation and deactivation delays, configurable
inverted activation of the relay and configurable locked
alarms
(see section 1.12.8)
.
Front protection IP65. Connections by plug-in screw ter -
minals. For industrial applications.
Functions included :
• tare accessible from frontal key or rear contact
(see sec-
tion 1.11)
• automatic ‘auto-tare’ function
(see section 1.12.4)
• access to gross weight value and tare value
(see sec-
tion 1.9.5)
• function ‘ On Power Up ’ for automatic activation of
functions at start-up
(see section 1.12.14)
• scale factor for easy modification of reading units
(see
section 1.12.5)
• ‘stock units’ function to count units
(see section 1.12.6)
• access to the measured signal value (in mV), excitation
current provided (in mA) and real excitation voltage
(see
section 1.12.13)
• configurable ‘ Fast access ’ menu (key ‘UP’ (
5
)) with
access to selected functions
(see section 1.12.13)
Multiple display filters, memory for maximum and mini -
mum, password, 5 configurable brightness levels.
1. Power and signal connections
- connect the power
(see section 1.8)
- connect the signal
(see section 1.8)
- read recommendations to connect the ‘sense’
(see section
1.8.1)
and for load cell ground connections
(see section
1.8.2)
2. Initial setup
(see section 1.12.2)
- theoretical configuration of the cell (obtain the load cell
data : sensitivity, load and excitation) and configure the
instrument
- apply the empirical configuration of the cell (apply the
high and low ‘field correction’)
- assign the ‘system zero’
3. Advanced configuration (optional)
(see section 1.12.7)
- tare configuration, see sections
1.11
and
1.12.4
