LED ERROR - OUTPUT RELAYS
CONTROL ECOWATT models include an LED "ERROR" on the front panel and in the circuit of
the two relays RL1 and RL2. They have the following functions:
The function of relay 1 (J13) is Alarm or Error, together with the LED “ERROR”.
Activation:
1. When all the sensors read 0 for 2s. The J13 relay is locked and the LED “ERROR” is lit.
“S1 ERROR” appears on the display.
If this happens, check the sensor connections that show "error" on the display.
2. In the PROPORTIONAL setting, when the alarm sensor limits are exceeded (S1 ALARM,
S2 ALARM, S3 ALARM). The LED “ERROR” flashes twice. “S1 ALARM” appears on the
display.
The function of relay 2 (J5), in the MIN-MAX setting, is to activate the high speed of a two-
speed motor (2-windings single phase motor) when there is a change of input
