Output 2 [Fan] - Fan ON / OFF
This output is activated whenever the air cooler fan has been turned ON.
Output 3 [Pump] - Pump ON / OFF
This output is activated whenever the air cooler pump has been turned ON.
Output 4 [Ext] - External Control
This output is activated whenever the air cooler is under external control.
Output 5 [Fault] - Fault ON / OFF
This output is activated whenever the air cooler is in a fault condition. Refer to Installation and Operation manual,
SERVICE [SERVICE] Mode, page 8
for more details about faults.
Output 6 [S.Hum] - Serial Humidity
This output is activated whenever the air cooler has been turned ON or is in Standby Mode. The binary information
represents humidity as a percentage. The bit stream is described on page 4.
For example, consider a relative humidity of 32%, the bit stream will be: -
00000000{00100000} Therefore read as 32%RH
32
Output 7 [S.Temp] - Serial Temperature
This output is activated whenever the air cooler has been turned ON or is in Standby Mode. The binary data
represents 10 x Temperature (in
° C). The bit stream is described on page 4.
For an example, consider a Temperature of 20.3
°
C the bit stream will be: -
0000000{011001011} Therefore read as 20.3
°
C
203
Output 8 [Drain] Drain Control Output
This output is activated whenever the Drain Valve is open. It will activate only after the time delay period set in the
IWC05 Program. The output will remain activated while the Drain valve is open. If the Drain valve opens for a
period of time less than the delay time set, the output signal will remain activated for 5 seconds only.
OUTPUT CONFIGURATION
IWC05 outputs 1,2,3,4,5 & 8 are switches only. They will function when
connected to a power supply from an external source of (1.4 - 32VDC at
40mA load).
Connect the external DC power supply to the load, connect the negative of
the load to the desired output terminal and connect the negative of the
power supply to the common [com] terminal on the IWC05. The output will
then turn on your load as desired (page 4).
Outputs
All outputs are indicators only of the state of the air cooler. None of them
are monitored for integrity. A fault on an output line is not indicated in the
IWC05.
Output 1 [ON] - System ON / OFF
This output is activated whenever the Air Cooler has been turned ON from
any source, in any mode.
