The following functions are available in the EXPERT MODE:

• Input of a preset for the internal universal counter

• Encoder voltage selectable

• Settings (e.g. dialogue language) programmable via parameters

2.4 Power Supply

Possibilities of powering PWM 8

• Line-powered via a separate 24V power supply unit (standard set)

• By an external, non-floating dc voltage source of 10 - 30 V / approx. 1 Ampere (adapter cable supplied

with PWM 8).

• Via the subsequent electronics; encoder, PWM 8 and subsequent electronics must be connected in

series (Caution: power consumption of PWM 8 approx. 5.5W).

The power supply of the measuring systems (external power supply unit or subsequent electronics) is

selected via the soft keys of PWM 8.

If a voltage is connected to the DC-IN socket of PWM 8, the PWM base unit is always operated with this

voltage.

If PWM 8 and/or the encoder are to be powered via the subsequent electronics,

• the encoder monitoring function of the subsequent electronics is active;

• it can be selected, how the encoder voltage of the subsequent electronics is fed to the encoder via

PWM 8:

1. directly to the encoder (via parameter: P2 in EXPERT MODE)

2. via the switching regulator (integrated in PWM 8) with potential segregation and possibility of setting

the encoder voltage.
