5 Options
The following options to the DF-760 are available at the time of order:
5.1
Key Lock
An optional key lock can be installed in the door of the analyzer to prevent access to the
power switch and other internal components. The lock is supplied with two keys.
If the analyzer is operating, the key lock does not prevent adjustments from the front panel.
5.2
Operating Voltage
The analyzer can be wired for operation at either 100-120 Volts AC or 200-240 Volts AC.
The operating voltage is not adjustable in the field.
5.3
Serial Communications
The analyzer can be set for communications by RS-232 or RS-485.
The serial communications option is not adjustable in the field.
See page 41, 113 and 114 for additional information.
5.4
Analog Voltage Output
The maximum analog voltage output can be set at the factory to 0-1, 0-2, 0-5 or 0-10 Volts
DC.
The maximum analog voltage output is not adjustable in the field.
See page 42, 65 and 97 for additional information.
5.5
Hydrogen Service Safety System
This option enables the analyzer to be safely used in a hydrogen background application.
See page 173 for additional information.
5.6
Vacuum Pump
An optional pump can be purchased to replace the aspirator in cases where there is
insufficient gas flow for the aspirator or when the analyzer is installed in a portable cart
and connection to an air supply is inconvenient.
NOTE: If a pump is being retrofitted to an analyzer configured with an aspirator, then the
aspirator assembly must be removed completely to uncover the pump power connector and
breaker switch. The pump connection should be made directly to the Moisture Sample
Outlet as described in section 5.6.2.
