Frequently Asked Questions - VAPZ Soler & Palau

How to install the VAPZ controller?

Mount the controller on a vertical wall in a technical room, with cable glands facing downwards. Leave sufficient clearance to dissipate heat losses. Connect the 220-240 V~ power supply with earth, and comply with standard NF C 15-100.

How to adjust the minimum voltage Smin?

Set the front panel switch to AUTO, the run/stop input to run, and switches S1.2 and S1.3 as follows: S1.2 OFF, S1.3 ON. Measure the motor voltage and adjust the Smin trimmer to the desired value (factory setting 110 V). Set S1.3 back to OFF.

How to adjust the maximum voltage Smax?

Set the front panel switch to AUTO, run/stop input to run, and switches S1.2 ON, S1.3 OFF. Measure the motor voltage and adjust the Smax trimmer (factory setting 230 V). Caution: if you want the maximum value, turn the trimmer until the voltage starts to drop.

How to configure the analog input (proportional mode)?

Set the front panel switch to AUTO, run/stop input to run, maximum speed input inactive. Switch S1.1 selects the signal type: ON for 0-20 mA, OFF for 0-10 Vdc. Then adjust Emin and Emax using the corresponding trimmers (measure between GND and the terminal).

How to use MINI/MAXI mode?

Set the front panel switch to AUTO, run/stop input to run, S1.2 and S1.3 to OFF. Use the maximum speed input terminals: open circuit = minimum speed (Smin), closed circuit = maximum speed (Smax). The Smin and Smax adjustments are made beforehand.

What to do if the motor does not start?

Check the power supply (220-240 V~, 50 Hz), the fuse status, and that the front panel switch is on AUTO or ON. In AUTO mode, ensure the run/stop input is closed. During startup, the output is forced to Smax for 8 seconds to start the motor.

How to power a sensor with the 24 Vdc output?

The SELV output provides 24 Vdc (100 mA continuous, 200 mA peak). Connect the sensor: for a 2-wire sensor, the 0-20 mA loop is powered by this output; for 3/4-wire, connect the signal output (0-10 V or 0-20 mA) to the analog input IN.

How to interpret the green indicator on the front panel?

The green indicator lights up when the motor output voltage is above 0 V, indicating that the motor is running.

What are the safety instructions for installation?

Installation must be carried out by a professional electrician in accordance with standard NF C 15-100. Disconnect the power supply before any intervention. Do not touch live parts (risk of death). Install a suitable magneto-thermal circuit breaker upstream and connect the earth.

How to maintain the VAPZ controller?

Maintenance is minimal: periodically check the tightening of electrical connections and that the ambient temperature remains within the range -10 °C to +50 °C. No specific cleaning is required.

USER MANUAL VAPZ Soler & Palau

Emin < Emax ≤ 10V DC

Si senal coriente: 0mA≤ Emin < 20mA

Emin < Emax ≤ 20 mA

By varying the supply voltage of the single-phase fan it is connected to, the controller changes the fan's rotation speed (squirrel-cage single-phase asynchronous motor).

INSTALLATION AND SETTINGS (see block diagram at the end of this notice)

1. LOCATION

We recommend installing the regulator in an equipment room. Wall-mount the regulator with the cable glands facing downwards, allowing enough clearance for heat to disperse.

2. POWER SUPPLY

Single-phase 220-240V AC + earth Frequency: 50Hz + / - 2Hz

3. CONTROL PANEL

• "OFF" => motor output = 0V on condition that max. speed input is not activated
• "AUTO" => motor output depends on the status of the inputs
• "ON" => motor output = max. voltage (in accordance with Smax setting).

4. INPUT GO/STOP

Condition = panel switch set to auto:

• circuit open between the 2 terminals => stop
• circuit closed => on (motor output depends on IN analogic input status)

At powerup, motor output is forced to max. value for 8s to set the motor running.

5. INPUT MAX. SPEED

Always takes priority regardless of the position of the panel switch and the status of the go/stop and IN inputs:

• Circuit open between the 2 terminals => input inactive (motor output depends on analogic input).
• Circuit closed motor output = max. voltage (in accordance with Smax setting).

6. PROPORTIONAL MODE (VAV): ANALOGIC INPUT IN

Condition = front panel switch set to AUTO, "ON/OFF" input set to ON and "Max. speed" input inactive.

Changes in motor output depend on this input:

Motor output [V AC]

2 types of signal possible for analogic input:

• current signal 4-20 mA if switch S1.1 set to ON (factory setting)
• voltage signal 0-10V DC if switch S1.1 set to OFF

Emin and Emax settings:

Factory settings: Emin = 7.2 mA; Emax = 14.4 mA

These settings are for connecting a C02 sensor.

• Range of possible settings:

If signal voltage: 0V≤ Emin < 10VDC

Emin < Emax ≤ 10V DC

If signal current: 0mA≤ Emin < 20mA

Emin < Emax ≤ 20 mA

To change the factory settings:

Example "Emin":

• Connect a voltmeter (DC voltage) between GND and Emin.
  -Factory setting = 2.12V
• Using a fl at-headed screwdriver, rotate the trimmer marked " Emin" (e.g. until the voltmeter indicates 2V).
• The value matches Emin/4 if analog input = current.

(Example = a reading of 2V means Emin = 2 x 4 = 8 mA; i.e. as long as the IN input is lower than 8 mA the motor output is Smin)

• The reading is Emin/2 if input = voltage.

[Example = a reading of 2V means Emin = 2 x 2 = 4V; i.e. as long as the IN input is lower than 4V the motor output is Smin].

For "Emax": proceed in the same way, connecting the voltmeter between GND and Emax and adjusting the trimmer marked "Emax".

[Example = a reading of 4V means Emax = 4 x 4 = 16 mA; i.e. as soon as input IN is higher than 16 mA the motor output is Smax].

7. MOTOR OUTPUT: SMIN AND SMAX SETTINGS

Factory settings (+/- 20V) for 230V supply voltage: Smin = 110V; Smax = 230V.

• Range of possible settings:

90V ≤ Smin<regulator supply voltage.

Smin < Smax ≤ regulator supply voltage.

• To change the factory settings:

• Measure the motor output voltage.

• Motor output can be forced using switches S1.2 and S1.3:

Condition = front panel switch set to auto and max. speed input inactive

S1.2 S1.3 Output motor
OFF	OFF	Automatic (non-adjustable)
ON	OFF	Smax forced
OFF	ON	Smin forced*
ON	ON	Automatic (non-adjustable)

• Adjust Smax by turning the trimmer marked "Smax" important: if the desired Smax setting = max. value permitted by the supply voltage (around 230V) set the Smax trimmer to the point where the motor voltage begins to fall.
  ** Adjust Smin by turning the trimmer marked "Smin".

8. MIN./MAX. MODE:

Conditions:

• Frontal panel switch set on "AUTO".
• Input "ON/OFF" set to ON.
• Switches S1.2 and S1.3 set to OFF.

Smin value setting:

Being switch S1.2 set to OFF and S1.3 in ON, to measure output motor voltage. Adjust Smin potentiometer until to obtain voltage value desired (factory setting 110V). Finally, adjust switch S1.3 in OFF position.

Operation:

To use two terminals commented on section 5 [Max. speed] to generate a MIN/MAX mode depending on input digital signal (CPFL, SC02-AR,...).

• Circuit open between two terminals => output voltage motor corresponds to minimum speed Smin (factory setting 110V).
• Circuit closed: output voltage motor corresponds to maximum speed Smax (factory setting 230V).

9. OTHER OUTPUTS

SELV 24V DC output:

Max. current = 100mA in permanently (200mA for 1 second peak every 30 seconds).

Can be used for powering a sensor using:

• 2 wires = current measurement signal 4 - 20mA circulating on supply loop,
• 3/4 wires (output voltage 0-10V DC signal or current 0-20 mA signal).

In both cases, the sensor output should be connected to the regulator analogical input IN.

Relay output:

Free voltage contact normally closed if motor output >0V

Cutting capacity at 250Vac = 10A (Cos Fi=0.6) / 16A (Cos Fi=1).

10. GREEN INDICATOR LAMP ON FRONT PANEL:

Indicates that motor is running (clear when motor output is >0V ).
