Installation and operating instructions Wilo-Stratos GIGA, GIGA-D, GIGA B
During initial commissioning, the pump will work with the factory
settings.
• The service menu deals with the setting and converting of individual
pumps; see chapter 8 "Operation" on page 97.
• To correct faults, also see chapter 11 "Faults, causes and remedies"
on page 121.
• For additional information about the factory settings, see chapter 13
"Factory settings" on page 131.
CAUTION! Risk of property damage!
Modifying the settings for the differential pressure sensor can lead
to malfunctions. The factory settings are configured for the sup-
plied Wilo differential pressure sensor.
• Default values: Input In1 = 0 – 10 volts, pressure value correction =
ON.
• When using the supplied Wilo differential pressure sensor, these
settings must not be changed!
Modifications are only needed if another differential pressure sen-
sor is used.
At high ambient temperatures, the thermal load on the electronic
module can be reduced by lowering the switching frequency (menu
<4.1.2.0>).
NOTICE:
Carry out the switchover/change only when the pump is at a standstill
(not when the motor is running).
The switching frequency can be changed via the menu, the CAN bus
or the IR-Stick.
Lower switching frequencies result in increased noise levels.
If the menu <5.7.2.0> "Pressure value correction" is not available on
the display of a given pump, that pump is a variant in which the fol-
lowing functions are not available:
• Pressure value correction (menu <5.7.2.0>)
• Efficiency-optimised activation and deactivation in twin-head
pumps
• Flow rate trend display
DANGER! Risk of fatal injury!
Incorrect installation and improper electrical connections can pose
a risk to life and limb.
• Have the electrical connections set up by qualified electricians
only, in compliance with the applicable regulations!
• Adhere to accident prevention regulations.
DANGER! Risk of fatal injury!
Failure to install safety devices on the electronic module or near
the coupling/motor can cause electrical shock or contact with
rotating parts, potentially resulting in life-threatening injuries.
• Before commissioning, all safety devices such as module covers
or coupling covers that were removed must be reinstalled!
