5. Before starting the trial run.
Please execute the following confirmations to prevent wrong connection.
If there is wrong connection, it may damage fan controller, but also damage the unit.
Confirmation
Please intercept the power supply without fail, and secure safety when you execute detaching wiring, the connector,
and the measurement machine to the following work.
Step
Step 1
Confirmation matter Check Correspondence
Connected
confirmation
Step 1-1 Is fan controller's power supply input wiring position connected correctly as
shown in installed manual?
Step 1-2 Is the phase of the connection of fan controller power supply input (TB IN)
accurate?
Step 1-3 Is the phase of the connection of fan controller output (TB OUT) accurate?
Step 1-4 Is the phase of connection of fan controller output wiring to fan motor accurate?
Step 2
Drive confirmation
Step 2-1 Does the fan rotate in a correct direction, when the unit is driven ?
Step 2-2 The thermistor for the condensing temperature detection is removed to CN01.
Drive to the cooling operation.
(The unit stops abnormally when the cooling operation drive is continued for a
long time occasionally. - High pressure switch off)
Whether LED01 has blinked is confirmed.
When the unit is in operation, the fan controller output voltage measured
in TB OUT, and checked whether the output of about 200V.
There is a problem when it is an output of about 300V.
Step 2-3 The thermistor for the condensing temperature detection is surely connected
with CN01 as before.
Step 2-4
Step 1-5 Is the thermistor for the condensing temperature detection of the attachment
connected with CN01?
Step 1-6 Is the thermistor for the condensing temperature detection accurately installed
in the unit?
Step 1-7 In case of the heat pump model, the wiring for full load input is connected with
CN04?
In case of the heat pump model and the heating drive is possible, the heating
drive is executed and the voltage of CN04 is input AC198V - 264V.
In that case, the fan must be full load drive.
(The output of the power-supply voltage is confirmed in TB OUT. )
When heating cannot be driven, step 1-7, step 1-8 is executed again.
In case of the heat pump model, the wiring for full load input is connected
accurately in control box?
