Installation and operating instructions SIE, DIE, PBE
• After acknowledging the fault display, the status display will be
shown on both pump displays for the duration of the communication
interruption. This resets the ESM/SSM contact at the same time.
• The slave pump display will show the symbol (
emergency operation).
• The (former) master pump continues to have control. The (former)
slave pump follows the emergency operation settings. Emergency
mode can only be exited by triggering the factory setting, eliminating
the interruption in communication or by switching the mains off/on.
NOTE:
During communication interruptions, the (former) slave pump cannot
run in auto control, since the differential pressure sensor has switched
to the master. When the slave pump is running in emergency opera-
tion mode, changes cannot be made to the electronic module.
• After the end of the communication interruption, the pumps will
resume regular dual pump operation as before the malfunction.
Leaving emergency operation at the slave pump:
• Factory settings restored
During a communication interruption on the (former) slave, if emer-
gency operation is discontinued because the factory settings have
been restored, the (former) slave will start up with the factory settings
of a single pump. It will then run in Δp-c mode at about half the max-
imum delivery head.
NOTE:
In the absence of a sensor signal, the (former) slave will run at maximum
speed. To prevent this, the (former) master's differential pressure sen-
sor signal can be looped through. When the double pump is operating
normally, it is not affected by sensor signals pending on the slave.
• Mains off, mains on
During a communication interruption on the (former) slave, if emer-
gency operation is discontinued due to mains off, mains on, the
(former) slave will start up with the latest emergency operation set-
tings received from the master (for example, control mode with pre-
set speed or off).
Leaving emergency operation at the master pump:
• Factory settings restored
During a communication interruption on the (former) master, if the
factory settings are restored, it will start up with the factory settings
of a single pump. It will then run in Δp-c mode at about half the max-
imum delivery head.
• Mains off/mains on
During a communication interruption on the (former) master, if emer-
gency operation is discontinued due to mains off, mains on, the
(former) master will start up with the latest settings it has from the
double pump configuration.
A particular pump can generally be enabled or disabled in terms of
operation in menu <5.1.4.0>. A disabled pump cannot be used in
operation until the disabling has been manually lifted.
The setting can be made at each pump directly or over the infrared
interface.
