5.1.5 Factory settings
The pump can be reconfigured to its original factory settings with one serial command.
To reset the motor controller to factory settings, send the following command:
Command ! C 8 2 1 sp 1 cr
The reply will be as follows:
Reply * C 8 2 1 sp r cr
The factory settings are restored in the memory within the pump. A Power cycle may be
required if either valve type setting was previously configured to a non-default setting.
5.1.6 Assigning a multi-drop address
Each individual pump must be programmed with its own multi-drop address via a point-
to point connection before introduction into a multi-drop network.
When the pump is shipped, multi-drop mode is disabled by default.
Send the following command to assign a multi-drop address (where the 'd' characters
represent the address):
Command ! S 8 0 0 sp d d cr
Note:
The address can be a decimal number from 1 to 98. The address number 0 is used to
disable multi
‑
drop mode. The address number 99 is reserved as a wild card and is used in
the query set up detailed later.
The reply will be as follows:
Reply * S 8 0 0 sp r cr
The multi
‑
drop address is stored in the pump.
A query can be sent to the pump to find out if it has a multi-drop address. Send the
following command:
Command ? S 8 0 0 cr
If the reply is as follows, the pump has multi
‑
drop mode disabled:
Reply = S 8 0 0 sp 0 cr
If the pump already has a multi-drop address, there will be no reply. Communicate with
the pump in multi-drop message protocol. Refer to Operation with multi-drop on page
58 for more information about multi-drop mode and multi-drop message protocol.
Use the following query (using wild card address 99 which means ‘any’ node) to find out
the multi-drop address of the pump:
Command # 9 9 : 9 9 ? S 8 0 0 cr
The reply will be as follows, where dd shows the multi-drop address of the pump:
Reply # 9 9 : 9 9 = S 8 0 0 sp d d cr
