Operation 4
Alarm
The alarm is a buzzer which sounds every time
there is an error or an invalid setting entered or
encountered. It can be programmed to be either On
or Off. This function only controls the operation of
the buzzer, it does not affect the operation of the
pump when there is an error.
If the alarm is set to be On, the warning buzzer
will sound every time an error is encountered. An
error can be a pressure limit encountered, an
invalid setting, or a pump absent. This setting can
be changed from On to Off by pressing the soft key
under Change.
# The default setting is Off.
• Select the option you want and press the Next
soft key to go to the next menu.
GSIOC Unit ID Number
Each pump in a multipump system has to have an
identification number to distinguish it from other
pumps and equipment connected to the GSIOC
communications channel.
When using a 305 Master pump, you must have
the identification numbers detailed in the table
above for the slave pumps. The Master pump can
have any number between 0 and 63, however the
default value of 1 is recommended for simplicity.
# The default value is 1.
• Key in the identity number you require for this
pump and press Enter.
Output Contacts (Ouptut #xx is Open / Closed)
There are three relay outputs in the 305 Master
pump numbered 1, 2, and 3. These outputs can be
used to control other instruments. They can be
programmed to open and close during a method
run. They can also be opened and closed manually
using soft key commands.
To change the state of an output, key in the number
of the output, for example output # 2. When you
press Enter, the display will show the present state
of output 2, i.e. Output # 2 open/closed. Press the
soft key Change to change the state of the output.
Do not set the Master pump ID
number to 2, 3 or 4 as these
numbers are reserved for the
Slave Pumps and Injection
Pump.
