b) "Fixed speed" (unregulated mode): in this mode the
setting button does not pulse, but remains constantly
illuminated.
preset curves at "proportional differential pressure"
and three curves at "fixed speed". The button lights up
with the colour that indicates the selected level. The
sequence is "blue-green-yellow": the blue indicates the
lowest speed/differential pressure curve, the yellow the
maximum speed/differential pressure curve
How to set different operating curves and how to switch
between the 2 modes
(regulated mode – recognizable by the pulsating button),
a short pressing of the button will change the operating
curve according to a.m. sequence (blue-green-yellow).
"fixed speed" (unregulated mode) it is necessary to press
the setting button for at least 5 seconds: in this way
the button will remain constantly lit (thus indicating the
fixed speed mode has been set) and the current speed
curve set will be according to the colour selected before
long pressing the button. Shortly pressing the setting
button will set the pump back to "proportional differential
pressure" mode. In order to change the speed curve
(in "fixed speed" operation) it is therefore necessary to
select the requested curve while in "regulated mode"
and after that to switch to the "fixed speed mode" by
long pressing the setting button.
NOTE: the hydraulic response in the regulated mode is
proportionate to the flow. The set head for single chosen
level has an inclination angle of 50% (see table below).
10.2 PUMPS Ego ER-/40, 60, 80 – CONTROL BY
ANALOG SIGNAL
The Ego ER -/40, 60, 80 are equipped with an additional
module that allows
controlling the pump with an analogue signal 0 -10 V.
"Unregulated mode" (fixed speed)
14. TROUBLESHOOTING
DESCRIPTION OF THE ERROR
INDICATOR LIGHT IS OFF, PUMP IS NOT WORKING
INDICATOR LIGHT IS PERMANENTLY ON
INDICATOR LIGHT CHANGES COLOUR
NOISES COMING FROM THE PUMP/THE HYDRAULIC SYSTEM The pump or the system are not properly vented
FLOW RATE TOO LOW
15. DECLARATION OF CONFORMITY
The company EBARA PUMPS EUROPE S.p.A. declares
under its own responsibility that its Ego products are in
conformity:
2006/42/EC (MD), 2004/108/EC (EMC),
2006/95/EC (LVD), EN 809,
EN 60 335-1, EN 60 335-2-51,
EN 61000-6-3, EN 61000-6-1
signal. This mode is set by pressing and holding the
button on the primary circuit for 5 seconds (the light is
on). If the value of the controlling signal is lower than 1
V, the pump enters in a stand-by mode. See diagram
at the end of this manual.
"Regolated mode" (proportional differential pressure)
value of the controlling signal. If the value of the controlling
signal is lower than 1 V, the pump enters in a stand-by
mode. See diagram at the end of this manual.
External control works only if the input resistance is <
10k . In this case, the input voltage must be considered.
If the input resistance is > 50 k , the pump will operate
as a standard version without external control.
11. MAINTENANCE AND REPAIR
Often control the plant trying to eliminate the disturbing causes
such as sand, lime, etc. Keep efficient the parts exposed
to damages (valves, filters, detectors and protections). For
interventions always call qualified technicians.
In case of long rests provide to often start the electropump.
Any replacement of the feeding cable as well as all other
maintenance operations must be performed only by the
assistance centre.
12. DEMOLITION
When demolishing the electropumps, follow strictly the
regulations in force in your country.
The user is responsible for disposing the equipment by
delivering it to a collecting point for recycling and disposal
of electrical equipment.
For further information about the collecting points of
equipment, contact your local authority for waste disposal,
or the shop where you purchased your product.
