At each power-on of the pump unit, an automatic air venting proce-
dure is executed. During this phase, the user interface displays "deg"
(degassing) and a count-down begins until the completion of the pro-
cedure.
The air venting procedure can be recalled or skipped:
• Manually by pressing simultaneously the two buttons (5). See User
interface on page 9. The feature will remain disabled until power to
pump is disconnected.
The procedure can be permanently enabled or disabled by:
• Manually by pressing simultaneously the two buttons (5) for at least
10 seconds. See User interface on page 9. Or
• Via communication bus. See the electronic drive manual on
www.bellgossett.com.
6.2.2 Two pumps in parallel configuration setup
The circulators are configured as single units by factory default. To acti-
vate the two pump parallel functions, follow the procedure below only
on one of the two pumps. The second pump will be automatically con-
figured. The working modes are described in Automatic two pumps in
parallel operation on page 11.
6.2.3 Set automatic operation mode on two pumps in
parallel
Once the communication cable is connected, configure only the “lead”
pump. The two pump submenu for this configuration is available at
each power-on. When the drive is displaying SING (which stands for
“Single Pump) short press one of the settings button (5) to display two
pumps in parallel menu.
The following procedure must be executed during the start-up phase
of the pump.
1. Enter the two-pump sub menu when the display is showing TWMA
(two-pump master) or TWSL (two-pump slave).
2. Select the applicable two-pump operation.
– bcup = backup operation
– alte = alternative operation
– para = automatic parallel operation
– forc = forced parallel operation
3. Push the parameter button (3) to accept the new setting.
The second pump is configured automatically by the lead pump. Refer
to Electronic Drive Manual for further details.
