1.4 Signalling controller status
In a right lower corner of the controller there is a LED indicating the controller's operation mode:
1. LED switched off – controller is not connected to power supply
2. Green light blinking – correct operation, controller controls AHU operation
3. Green and red light blinking - program stopped (see program „Scope”)
4. Red light – controller error
!
1. All control boxes from the VS…CG ACX36 typeline need to be powered from the main switchgear
equipped with appropriate protection of wires powering the control box.
2. Connection and start-up of the control gear should by done by qualified staff only.
Without additional elements the control gears can work inside a building. Assembly outside in a
moderate climate is permissible if an additional heating module is assembled. The X0:4,N clamps are
designed for this module. (230V, 6A)

2. SYSTEM START-UP
CAUTION!
!
Operation of the AHU is strictly arrested by the fire-protection alarm, activation of the thermal
protection of fans' motors, threefold activation of the protection of electric heater and threefold
activation of the anti-frost thermostat. Each of these events requires removing the cause of the
alarm and then canceling it (see more details in „Advanced Manual” chapter).

interpreted by the system as the Summer and blocks the AHU heating cycle, short contact is interpreted as
the Winter and the cooling is blocked.
TeOc - Function forcing AHU operation in normal mode during one hour from the contact shorting

Selecting functions of the X3 (B5) multifunctional analog input.
NoFu - signal sent to the input is ignored by the controller
TeSp - input signal is interpreted by the system as the preset temperature value omitting settings of both
control panels - VS 00 HMI Basic and VS 00 HMI Advanced. Input is adapted to operation with a passive
resistance element scaled as the input of PT 1000 temperature sensors, i.e. 1000 Ohm = 0 oC
ReRt - input signal is interpreted by the system as the preset recirculation level value omitting settings of
the HMI Advanced
FrSp - input signal is interpreted as the preset frequency value. The input receives voltage signal 010VDC, where 0V = minimal frequency, 10V = rated frequency.
(see MENU SERVICE ACCESS FAN SETTINGS SUPPLY... and ... EXHAUST)
If minimal frequency of supply and exhaust fan vary, then range of the proportional control is between
nominal frequency and minimal frequency with higher value. Further lowering of the signal causes lowering
of frequency only of the converter with lower minimal value of the preset frequency.

The alarm is displayed as a code, where temperature is indicated.
30.01, 30.02 and 30.03 alarms are displayed alternately with the
temperature value from the main control sensor.
The panel does not support cancellation of alarm statuses.
An alarm can be cancelled using VS 00 HMI Advanced or by
switching off and on again power supply of the control gear.

!
In a sequence of alarm cancellation with power supply, turning power again on should be done no
sooner than the frequency converters displays are cleared - about 30 seconds from switching off.
!
Switching on the system again after cancelling motor alarm can be done as soon as the motors are
cold, i.e.: 10 minutes after the alarm occurred.
Alarm LED is blinking also in case of alarm status, which appeared and abated and which does not require
cancellation. Turning off the LED in such a case is carried out with alarm cancellation procedure.

Appendix 12 The application control schemes
The control schemes for separate application are on the CD plate delivered with AHUs.
In order to print the proper application scheme as the first one should find the application code on the
AHU’s technical data, next select „Control Aplication” from menu „AUTOMATICS” of CD plate and
next choose suitable code and leading sensor.
