Installation and operating instructions LRE-JRE
Slave discontinues emergency operation:
• 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 approximately half
the maximum delivery head.
NOTE
In the absence of a sensor signal, the (former) slave will run at maxi-
mum speed. To prevent this, the (former) master's differential pres-
sure 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 power cycling (mains Off,
mains On), the (former) slave will start up with the latest emergency
operation settings received from the master (for example, manual
control mode at a specific speed or off).
Master discontinues emergency operation:
• 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 approximately half
the maximum delivery head.
• Mains Off, Mains On
During a communication interruption on the (former) master, if emer-
gency operation is discontinued due to power cycling (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.
A pump kick takes place 24 hours and 2 minutes after a pump or pump
head stops operating. The reason for the standstill is not important
(Manual off, Ext. off, Fault, Adjustment, Emergency operation, BMS
setting). This procedure is repeated until the pump is switched back
on via a control mechanism. The "pump kick" function cannot be dis-
abled via the menu or any other interfaces. As soon as the pump is
switched on via the control system, the countdown to the next pump
kick is interrupted.
A pump kick lasts 5 seconds, during which the motor turns at mini-
mum speed. If both pump heads on a double pump are switched off,
for example, via Ext. Off, both will run for 5 seconds. Pump kick takes
place even in "main/standby operation" mode if pump cycling takes
longer than 24 hours. In the event of a malfunction, the system will
also attempt to perform a pump kick.
The time remaining until the next pump kick can be seen on the dis-
play in menu <4.2.4.0>. This menu is only available when the motor is
stopped. The number of pump kicks is shown in menu <4.2.6.0>.
With the exception of warnings, all faults detected during a pump kick
will cause the motor to be switched off. The corresponding fault code
is shown on the display.
