Interferences in the interaction of all components may affect the

function of electronic devices. One interference factor is disabling

inductive loads, like coils of electromagnetic switching devices.

When disabling such a device, high switch-off induced voltages

may occur, which might destroy adjacent electronic devices or

result interference voltage pulses, which lead to functional faults,

by capacitive coupling mechanisms.

Since an interference-free switch-off is not possible without addi

tional equipment, the relay coil is connected with an interference

suppressing circuit.

If 24 V (coupling) relays are used in an application, it is required to

connect a protection circuit to avoid interferences.

Advantages and disadvantages of different interference sup

pressing circuits are as follows

All parameters are assigned a unique parameter identification

number.

The parameter identification number may be used to reference

individual parameters listed in this manual

The controller utilizes a password protected multi-level configura

tion access hierarchy. This permits varying degrees of access to

the parameters being granted by assigning unique passwords to

designated personnel.

A distinction is made between the access levels as follows:

f the mains rated voltage is 400 V, the upper voltage limit is 110 %

(of the mains rated voltage, i.e. 440 V), and the hysteresis for the

upper voltage limit is 5 % (of the mains rated voltage, i.e. 20 V), the

mains voltage will be considered as being out of the operating

limits as soon as it exceeds 440 V and will be considered as being

within the operating limits again as soon as it falls below 420 V

(440 V – 20 V).

If the rated system frequency is 50 Hz, the lower frequency limit is

90 % (of the rated system frequency, i.e. 45 Hz), and the hyste

resis for the lower frequency limit is 5 % (of the rated system fre

quency, i.e. 2.5 Hz), the mains frequency will be considered as

being out of the operating limits as soon as it falls below 45 Hz and

will be considered as being within the operating limits again as

soon as it exceeds 47.5 Hz (45 Hz + 2.5 Hz)
