6.4.3 Operation during interruption of
communication
Installation and operating instructions • Wilo-Stratos GIGA, Wilo-Stratos GIGA B • Ed.01/2023-05
Behaviour of the inputs and outputs
Actual value input In1, setpoint input In2.
• At the main pump: Affects the entire unit.
"External off"
• At the main pump (menu <5.1.7.0>): Depending on the setting in menu <5.1.7.0>, affects
only the main pump or the main and partner pump.
• Set at the partner pump: Only affects the partner pump.

Fault and run signals
Individual (ESM) or collective (SBM) fault signal:
A collective fault message (SSM) can be connected to the main pump for a central control
station. The contact may only be assigned to the main pump. The display is for the whole
unit.
The contact must be made to each pump for individual fault signals.
On the main pump (or via IR-Stick) this signal can be programmed as a single (ESM) or col-
lective (SSM) fault signal in menu <5.1.5.0>.
The EBM/SBM function can be set to "Standby", "Operation", "Mains on" in menu <5.7.6.0>
on the main pump.
NOTICE
"Readiness" means: The pump could run, there is no fault.
"Operation" means: Motor turning.
"Mains on" means: Mains voltage is present.
NOTICE
If the "Operation" function has been selected for EBM/SBM, each pump
kick issues a signal for a few seconds.
Operating options at the partner pump
The only settings that can be made at the partner pump are "External off" and "Lock/unlock
pump".
NOTICE
If an individual motor is disconnected from the power supply in twin-head
pump operation, the integrated twin-head pump management is out of
operation.
In the event of a communication interruption between two pumps in twin-head pump op-
eration, both displays show error code "E052". Both pumps behave as single pumps for as
long as the interruption lasts.
Both electronic modules report the malfunction via the ESM/SSM contact.
The partner pump runs in emergency operation (constant speed) at the emergency opera-
tion speed previously set on the main pump (see menu items <5.6.2.0>).
The emergency operation speed factory setting is equivalent to about 60% of the pump's
maximum speed.
• For 2-pole pumps: n = 1850 rpm
• For 4-pole pumps: n = 925 rpm
After acknowledging the fault display, the status display will be shown on both pump dis-
plays for the duration of the communication interruption. This resets the ESM/SSM contact
at the same time.
The symbol (pump running in emergency operation) flashes on the partner pump's dis-
play.
