Rotec ERGO-DigiStick - Operating Additional Solenoid Valves by Using a Rele

Operang Addional Solenoid Valves by Using
a Rele
Junior Power Timer (JPT) connectors B, C and D of the ERGO-DigiSck joysck's
steering cable can be used for operang external electrical components like
selector valves in a front loader. These coils normally need higher current than one
channel of ERGO-DigiSck can supply (2A). Therefor a rele is needed. Noce that
the signal to the terminals 85 and 86 is taken from the JPT connector. Using
external souces , plus or minus, will destroy the PCB card of the joysck!
NOTE: Very important to place a
diode to cut the high voltage
peaks caused by the coil!!
The cable of the JPT connector can be
cued and ABIKO cable shoes can be
pressed direct on the white and brown
cords. Also a male JPT connector can be
ordered from the manufacturer
B connector gives direct current C and D gives puls wide regulated current
(PWM) which makes the rele to "vibrate" on low currents. The vibraon will
disappear with full PWM. The vibraon can also be avoided by connecng a 100
μF condensator between terminals 85 and 86 on the rele. Noce that the
polarity has to be right when the condensator is used.
