Operating instructions

CAUTION

The pulled plug has mains voltage of the load circuit! The new connecting lines must be fused

according to the applicable regulations (for applicable plug, see chapter 13).

4.3 POWER SUPPLY FOR THE VENTILATOR

With Thyro-P Thyristor Power Controllers furnished with integrated ventilators (HF types), the venti-

lator must be supplied with a voltage of 230V 50/60Hz according to the connecting plans and the

dimensional drawings. The ventilator’s power consumption is given in chapter 11 TECHNICAL

DATA.

ATTENTION

The ventilator must run when the Power Controller is switched on.

4.4 RESET

The input RESET (terminals X5.2.12-X5.1.14) is separated from the remaining system by an opto-

electronic coupler. By opening the RESET jumper the Thyristor Power Controller is locked (load:

24V/20mA), i.e. the power sections are no longer triggered. On activating RESET, LED “ON” lights

up red.

Functional procedure:

TERMINALS FUNCTION

X5.12-14 closed Enables the device

X5.12-14 open Device is out of operation, communication via interfaces not possible

TAB. 8 RESET

The hardware RESET must be applied when synchronizing the software of several Power Controllers

(chapter 6.3 SOFTWARE SYNCHRONIZATION). If the Power Controller is equipped with a Bus

option, a Bus RESET also ensues from the hardware RESET. Apart from opening the jumper terminal

X5.2.12-X5.1.14, the hardware RESET is also activated by supply voltage OFF or by reducing the

supply voltage at the Power Controller (A70-X1) to below 160V.

4.5 CONTROLLER INHIBIT

The input controller lock (terminals X5.2.15 and X5.1.14) is electrically identical to the input RESET

(electrical data as under 4.4.).

ATTENTION

When activating controller lock, the LED „PULSE LOCK“ is lit and the control device remains com-

pletely in operation. The total set point is therefore without effect, but the min. limiting values (TS-

MIN, HIME) remain active. This enables securing a certain quantity of electrical energy at the load.

TERMINALS FUNCTION

X5.15-14 closed power controller operating

X5.15-14 open control pulses OFF (default value) or pulse limit

TAB. 9 CONTROLLER LOCK

All other functions of the power controller remain in operation. The state of the signalling relay

does not change (parameter-dependent) and communications remains active. After closing the

controller lock jumper, the controller is back in operation.

4.6 QUIT

The input acknowledge (Quit, X5.2.19) has a circuit identical with the input RESET. It must be
