Error Correction; Example Of Internal Circuit And Wiring - SMC Networks ZSE30 Series Manual

2-color Display Digital Pressure Switch
Description
Indication light (Green)
Displays the switch operation status.
UP button
Use this button to change the
mode or increase the ON/OFF set
value. It also allows you to switch
to the peak value display mode.
SET button
Use this button to switch the
mode and set the set value.

Error Correction

Take the following corrective solutions when errors occur.

Residual voltage:
Shut off the power
1 V or less
supply. After eliminating
the output factor that
caused the excess
current, turn the power
supply back on.

Output impedance:
back to atmospheric
pressure and try 1 kΩ
using the zero out
function.

supply pressure to 4 to 20 mA (±2.5% F.S.)
Maximum load impedance:
within the regulating
pressure range. Power supply voltage 12 V: 300 Ω
Power supply voltage 24 V: 600 Ω
Minimum load impedance: 50 Ω

PNP open collector
Shut off the power
Maximum 80 mA
supply. Turn the
power supply back
on.
If the power should
not come back on,
please contact SMC
for an inspection.

Series
LCD display
Displays the current pressure
condition, setting
conditions, selected display unit,
MPa
and error codes. A display color
type can be selected from either a
single color display with red or
green, or 2-color display in which
green and red are switched
according to the output.
DOWN button
Use this button to change the
mode or decrease the ON/OFF
set value. It also allows you to
switch to the bottom value display
mode.
