Description and function

6.1

Description of the pump

The pump (Fig. 1) consists of a hydraulic system, a glandless pump motor with a
permanent magnet rotor, and an electronic control module with an integrated fre-
quency converter. The control module receives an external PWM signal for speed
control. This version is equipped with an LED for displaying the operating status
of the pump see chap. 10.
6.2

Functions

External control via a PWM signal
The actual/setpoint level assessment required for control is referred to a remote
controller. The remote controller sends a PWM signal as an actuating variable to
the Pump.
The PWM signal generator gives a periodic order of pulses to the pump (the duty
cycle), according to DIN IEC 60469-1. The actuating variable is determined by the
ratio between pulse duration and the pulse period. The duty cycle is defined as a
ratio without dimension, with a value of 0 ... 1 % or 0 ... 100 %. See PWM signal
logic 1 (heating) Fig. 2a and PWM signal logic 2 (solar) Fig. 2b.
