4.4.3 Cautions on Control Circuit Wiring
Maintain wiring distance between pressure sensor and drive within 10m.
In case of remote control using analog signals, maintain distance between remote
control panel and drive within 50m.
Set off sensor and analog signal lines enough from power lines.
Use shield twisted wires for signal lines of control circuit.
Since GND are insulated, do not interconnect or ground them.
4.4.4 Connection of Pressure Sensor and Low Water Level Sensor
Use the pressure sensor and low water level sensor specified by IHM.
General specifications of the pressure sensor and low water level sensor specified by IHM are as
follows:
Category
Excited Voltage
Sensor Output
Pressure Sensor
DC 15V
4~20mA
Low Water Level Sensor
DC ±15V Pulse
Connection
Since terminals on pressure sensor have polarity, be careful about polarity during installation.
※
When you install the pressure sensor to pipings, please install the insulation between the pressure
sensor and pipings, in order to reduce the noise from pipings.
