CONTROL WIRING
Control wiring is provided for the ‘application menus’ offered with the ECODRIVE. Since all the Digital & analogue I/O is completely
programmable alternative wiring is possible. Refer to the ZENER 8000 manual for more detail and alternate wiring.
Solar Tank Fill Control Wiring
The following control wiring is recommended when the application for ‘Tank Solar’ or ‘Tank Solar AC’ is selected.
Input D2 (3): Tank level Switch:
This operates on having one level switch only installed. When
the water level is high the level switch opens and ECODRIVE
will stop the pump after the preset ‘qualifying’ time. This
ensures the tank is always full. When the water level falls and
the contact closes, the ECODRIVE is ready to restart.
Auto/Manual switch (if fitted or wired externally):
Auto: With this wiring configuration, “Auto” mode will control the load depending on the solar
intensity. If required, an additional run switch can be installed for remote start/stop or other
remote control. When there is sufficient Solar Power available the ECODRIVE will run on Solar,
and automatically switch off or changeover to auxiliary Ac supply when the solar intensity is
‘LOW’. When sufficient Solar intensity returns the ECODRIVE will automatically start or switch
back to Solar if running with an auxiliary AC supply.
Manual (LOCAL MODE) : “Manual” Mode allows control from the local console and with the
wiring shown, configured to operate from solar only.
Input D1 (2): Operating mode
Remove link for ‘Solar Only’ operation. The ECODRIVE will
run only when ‘SOLAR GOOD’ conditions are met. This will
prevent operation under low solar conditions. Install link for
“Solar & Auxiliary AC operation
Input Opt. D4 (37):
Bore/Well Level Probe/Switch:
Running completely dry can damage the pump. A probe
should be installed in the pump well to detect a loss of
water and turn off the pump before running dry. When the
water level is low the ECODRIVE will stop the pump. When
the water level returns and the contact closes, the
ECODRIVE will wait for the preset time and then restart.
AN1 (10,11) Irradiance Sensor Input
:
An irradiance sensor is optional for solar only but mandatory
with an Aux AC power supply.
Note:
“Local” Operation: “Local” mode normally
provides control from the front console and is
active when D4(5) is off / inactive. In local
operation the following inputs remain active.
•
D1(2) ‘Operating mode’
•
D2(3) Tank Level Control
•
Opt D4(37) Bore level protection
Suggested Control Wiring:
Input D3 (4): Run Input
Close to run when operating in AUTO/‘REMOTE Mode’
Input D4 (5): REMOTE/LOCAL Mode Selection
See AUTO/MANUAL below. Close for AUTO (REMOTE MODE).
REMOTE = AUTO & LOCAL = MANUAL
