Notes: 1. x =1 or 2, SPx ≥ RPx
2. Active electrical level is 2V lower than power supply level. Eg, power supply level is 24V, then active electrical level is 22V.

High level alarm
Output alarm signal when pressure is higher than 145Psi.
Normal setting: SP1=145Psi, RP1=137.78Psi, Mode1=1, SPDT1=1,
RPDT1=1. Pressure rises to 145Psi, delay 1s, OUT1 active (on);
pressure drops to 137.78Psi, delay 1s, OUT1 reset (off)
Output alarm signal when pressure is lower than 145Psi.
Normal setting: RP1=145Psi, SP1=152.28Psi, Mode1=2, SPDT1=1,
RPDT1=1. Pressure drops to 145Pssi, delay 1s, OUT1 active (on);
pressure rises to 152.28Psi, delay 1s, OUT1 reset (off)
Low level alarm
Starting devices normally requires pressure is within the range
72.51~145Psi. Normal setting: SP1=145Psi, RP1=72.51Psi, Mode1=3,
SPDT1=1, RPDT1=1. Pressure rises to 145Psi, delay 1s, OUT1 active
(on); pressure rises to 145Psi, delay 1s, OUT1 reset (off); Pressure
drops to 145Psi, delay 1s, OUT1 active (on); pressure drops to
72.51Psi, delay 1s, OUT1 reset (off)
Window function
Applying pressure on a device by a compressor and keeping the
pressure within the range 72.51~145Psi need two ways output. The
first way output controls the compressor and the second way output
controls the device. The first way output setting: SP1=130.53Psi,
RP=87.02Psi, Model=2, SPDT1=1, RPDT1=1. The first way contact
controls the power supply of compressor through intermediate relay
to disconnect once the pressure is higher than 130.53Psi and connect
once the pressure is lower than 87.02Psi. The pressure value needs to
be controlled within 87.02~130.53MPa. The second way output setting:
SP2=145Psi, RP2=72.51Psi, Mode2=3, SPDT2=1, RPDT2=1. Once
the working pressure of device is not within the range
72.51Psi~145Psi, after 1s, the second way contact controls the alarm
output of the device through intermediate relay to ensure the abnormal
working pressure of the device can be discovered and handled in time.
