CAREL in this case, through specific agreements, can intervene as consultant for the positive result of the final start-up machineapplication, but in no case can it be held responsible for the positive working of the final equipmentapparatus.

The keys must be connected to the connector (AMP 4 pin) envisioned in the controllers and can operate with controllers powered or not.

Carel Pco5 Controller Driver And The

The EVD driver and the IO board must be installed on DIN guide.

Note that with the same controller 3 different types of outputs can be obtained.

CONV010A0 - CONVONOFF0 module CONV010A0 module CONVONOFF0 module.

If the completed signal with green LED on is not given within this time period, it is good practice to attempt the operation again, releasing and pressing the button again.

In the event of flashing, see the relative table for the meaning of the signal.

Display The display features 3 digits, with the display of the decimal point between -99.9 and 99.9.

Outside of this range of measurement, the value is automatically displayed without the decimal (even if internally the unit still operates considering the decimal part).

Carel Pco5 Controller Serial Address Identifies

The serial address identifies the controller in a RS485 network with Carel or Modbus protocol.

The probe selected for the control depends on parameter r06, once enabled with the parameters 01 and 02.

The probe B3 can be configured as condensation temperature probe, external or differential control.

The external probe allows the activation of the external compensation algorithm.

The probe B4 can have the same functions as B3 and in addition acts as digital input (can be configured from par.

See parameter P42 at the Digital outputs paragraph.

In systems with hot gas bypass function enabled, the bypass valve is commanded by the output Y1 (controller) or Y2 (IO expansion board).

See the control chapter.

Compensation The compensation can indifferently increase or decrease the value of r01 depending on whether r17 is respectively positive or negative.

The anti-freeze set-point A01 represents the temperature below which the machine passes to anti-freeze mode: alarm A1 activates and switches the alarm output.

A03 is the intervention delay time of the anti-freeze alarm when starting the machine.

By delaying the connection, line overloads are prevented due to close or simultaneous peaks, c05 establishes the minimum time that must pass between the switch-off of the two compressors.

Par.

The resistances can be activated according to the relative set-points Par.

Depending on the type of fan, the controller PWM output (Y1), always active, requests the presence of optional boards: 1) CONVONOFF0 for the conversion of the PWM output into ONOFF output; 2) CONV010A0 for the conversion of the PWM output into 010 Vdc or 420 mA output.

The output enabled is the controller analogue output Y1 (water-water chiller) or Y2 (air-water chiller) of the IO expansion board.
