12.3.1 STANDBY MODE (MAX PRO MOD.)
In the operating mode with an external connection for the 0-10 V / PWM signal, the
Standby
mode is indicated by the
yellow LED (flashing slowly) turning on and
Stb
appearing on the display
FIG. 12
(Standby mode)
12.3.2 ANALOGUE INPUT
In the
external input
mode, the circulator accepts a direct voltage signal or a PWM, indifferently. The type of signal is
automatically selected by the circulator without the operator’s intervention.
12.3.3 0-10V INPUT
The circulator operates at variable speed according to the DC input voltage.
The circulator goes into standby at a voltage lower than 1.5 V.
The circulator operates at a variable speed, between 2 and 10 V, according to the voltage:
- 0% for voltage lower than or equal to 2 V
- 50% at 6 V
- 100% for voltage higher than or equal to 10 V
Between 1.5 V and 2 V, the circulator can be in standby or at minimum speed depending on the previous state
(hysteresis).
