Troubleshooting
ERR1
When adjusting zero point
while external pressure is
input.
Try again after removing
external pressure.
ERR2
When over current is
applied on control output
Remove the over current
conditions by adjusting load
resistance.
ERR3
When the range of Auto
sensitivity setting mode
ST1, ST2 is set incorrectly.
Check the setting range and
set
ST1
,
ST2
.
ERR4
When connection between
master and slave is wrong
during copying parameters.
Check the cables between
sensors and the connection
of the same models.
ERR5
When entering invalid
password.
Enter valid password.
HHHH
When applied pressure
exceeds the high-limit of
display pressure range.
Apply pressure within the
display pressure range.
LLLL
When applied pressure
exceeds the low-limit of
display pressure range.
-HH-
When the correction value
of auto shift, remote zero
exceeds the high-limit of
the setting range.
Set the correction value
of auto shift, remove zero
within the setting range.
-LL-
When the correction value
of auto shift, remote zero
exceeds the low-limit of the
setting range.
-HL-
When [
HH
], [
LL
] occur both.
This function is to diagnose malfunction of the system
caused by parasitic pressure through memorizing input the
max./min. pressure occurred from the system.
Press the
M
+
key more than 1 sec in RUN mode and set
the
Peak Hold.

Pressure unit change
PSQ series has 8 kinds of pressure unit.
Please select the proper unit for application.
• kPa, MPa, kgf/cm
2
, bar, psi, mmHg, inHg, mmH
2
O
※
When using mmH
2
O unit, multiply display value by 100.
It can prevent control output from chattering by changing
response time.
There are 10 types of response time; 2.5ms, 5ms, 10ms,
25ms, 50ms, 100ms, 250ms, 500ms, 1,000ms, 5,000ms.
If the response time is getting longer, the detection will be
more stable by increasing the number of digital filter.

SV display part
Select the display type at the SV display part in RUN mode.
There are 3 types; displaying SV [
STD
], displaying unit
[
UNIT
], none [
OFF
]
RESET
This function is to reset all parameters as factory default
except control output SV to prevent wrong settings or
difficult operation.
Password
This function is to limit parameter settings, to check the
parameter or to change the parameter settings only for
entering the set password.
•
0000: Password function OFF
• 0001: Only checking parameters
• Setting range: 0002 to 9999
Control output change
Select between NPN open collector output or PNP open
collector output.
PV display color and color linked output
You can select PV display color to the linked output status.
There are 4 types as below.
Select color linked output among [
OUT1
], [
OUT2
], or [
ALL
].
SV
PV display color
R-ON
Green in normal status. When the set color linked output
turns ON, it displays red.
G-ON
Red in normal status. When the set color linked output
turns ON, it displays green.
RED
Red is fixed.
GREN
Green is fixed.
Zero-point adjustment
The zero-point adjustment function forcibly sets the
pressure value to "zero" when the pressure port is opened
to atmospheric pressure. When the zero adjustment is
applied, analog output [Voltage or Current] is changed by
this function.
To set zero atmospheric pressure forcibly,
press the
+
keys over 1 sec in RUN mode with the
opened pressure port.
Key lock
The key lock function prevents key operations so that
conditions set in each mode.
ᆞ
Press the
M
+
key over 1 sec in RUN mode to lock
keys. The PV display part displays [
LOCK
], and the SV
display part displays [
ON
] for 1 sec and it returns in RUN
mode.
ᆞ
Press the
M
