Binary Outputs - Grundfos CIM 300 BACnet MS/TP Instructions Manual

6.3 Binary outputs

Binary objects are used for controlling the Grundfos booster system.
ID Object name
BO, 0 Set control source
BO, 1 Relay 1 control
BO, 2 Relay 2 control
BO, 4 Reset fault
BO, 5 Fault simulation
BO, 6 Copy settings to local
BO, 7 Relay 3 control
BO, 8 Relay 4 control
BO, 9 Enable max flow limit
H: For MGE model H or newer
For Multi-E with CIM in each pump: always send all commands (writings) to all pumps.
A TPED model H is essentially a Multi-E model H with two pumps.
20
R/W Notes
It sets the control source.
Set to 1 to enable control via BACnet.

1: Bus control
It controls relay 1 if bus control is enabled and relay 1 is
set to be controlled via bus.
W
0: Closed (default)
1: Open
It controls relay 2 if bus control is enabled and relay 2 is
set to be controlled via bus.
W
0: Closed (default)
1: Open
It resets alarm if bus control is enabled.
(It is triggered on rising edge.)
W
0: No resetting (default)
1: Resetting
It enables fault simulation.
W 0: Disabled (default)
1: Enabled
It copies remote settings to local pump settings.
0: Disabled
W
1: Enabled
If enabled, change BO from 0 to "1: Bus control".
It controls relay 3 if bus control is enabled and relay 3 is
set to be controlled via bus.
W
0: Closed (default)
1: Open
It controls relay 4 if bus control is enabled and relay 4 is
set to be controlled via bus.
W
0: Closed (default)
1: Open
