3.9.2 System Cooling
This screen is the System Cooling Main Menu. It shows status, metering and faults
for the cooling system. It also provides for automatic or manual control of pump
switching and tells which pump is active. A Cabinet 2 button will be present for
dual cabinet transmitters, DVL 4300 and DVL 5700.
3.9.2.1 Cooling System Control Panel
At the bottom of the screen is the Pump Control Panel. This panel would be grayed
out (inactive) for single pump systems. For dual pump systems there are only 2
choices to be made:
1.
Auto/Manual - This button should always be pressed as shown placing
the pump control in auto-switch mode. In this mode a pump failure will
automatically cause a switch to the redundant pump. Manual mode dis-
ables the automatic pump switching.
2. Pump A/B - This is the manual pump switch control. It can be used
only when in the Manual switch mode.
NOTE:
Pump switching from this control screen will only work if the Pump Control
Panel is in the REMOTE control mode. Placing the Pump Control Panel in
LOCAL mode disables the transmitter pump switching commands. To switch
pumps with the Pump Control Panel in LOCAL mode, press the Pump A or
Pump B switches which are physically located on the Pump Control Panel.
For more information on the Pump Control Panel see "4.6.4 Pump Control
Panel" on page 4-40.
