threshold for the maximum allowable pressure loss. We will also try
to analyse the minimum pressure that occurs while all three fuel
valves are open and all pumps are running to detect heavy leakages
even in the monitoring gaps but we do not have this data yet. With
the planned protocol the heads will inform the Pump Station about a
detected leakage so that the Pump Station can depressurize
everything and enters Fail Safe afterwards. Now the Pump Station
goes into Fail Safe only if an internal leakage has been detected.
61. In case of a Fail Safe condition a hard reset is required. You
need to switch off the Pump Station, wait some seconds and the
power-up the unit again.
62. If the Pump Station is switched on the device measures the
system pressure and runs a depressurising cycle if more than 0,3 bar
are detected.
63. Depressurise the system before you dismantle the setup. Use the
menu function for this purpose.
64. With any pump action or fuel level measurement, the tank
ventilation valve will be opened. Gasiform IPA might be set free
during that due to the high vapour pressure of IPA. The warmer the
IPA the more serious this problem becomes. Take all necessary safety
measures to prevent dangerous situations arising from that. With
Isopar L this problem is less critical.
65. DMX is not decoded by the Pump Station but only by the Flame
Heads. The Pump Station is only used to distribute DMX to the Flame
Heads. In order to maintain a line shaped network architecture, the
signal from the DMX input is routed first to Flame Head 1, then back
to the Pump Station, then to Flame Head 2, again back to the Pump
Station, then to Flame Head 3 and then back to the Pump station to
be present on the output again for daisy chaining the DMX signal to
the next device. If only two or only one Flame Head is connected the
Pump Station bridging the data ports of the unused heads is
necessary. In order to route the signal correctly you have to
select the appropriate DMX routing in the menu of the Pump Station.
Only the following setups are possible: Head 1 + Head 2 + Head3 or
Head 1 and Head 2 or solely Head 1. It is planned to implement a
Flame Head detection function so that the device selects the correct
signal routing automatically.
