System Installation and Startup
2.1.3.5
Analog Voltage Output
Connections from the Analog Voltage output to the user’s auxiliary equipment are made at t
erminal block
TB3 on the rear of the analyzer chassis. Be certain to match the terminal pins against the terminal ID label
on the top of the analyzer chassis.
Use 20-AWG, 2-conductor, stranded-wire, twisted pairs for the connections. It is not necessary to use
shielded cable for the Analog Voltage output, with or without electrical barriers. If shielded cable is used, it
should be drained to dc ground at the auxiliary equipment.
2.1.3.6
Analog Current Output
Connections from the Analog Current output to the user
’
s auxiliary equipment are made at terminal block
TB3 on the rear of the analyzer chassis. The Analog current output is a negative ground, non-isolated 0-
20mA, or 4-20 mA current loop. 12 VDC Power is supplied by the Model 5100E analyzer. Maximum
electrical loading is 250 Ohms. Be certain to match the terminal pins against the terminal ID label on the
top of the analyzer chassis.
Use 20-AWG, 2-conductor, stranded-wire, twisted pairs for the connections. It is not necessary to use
shielded cable for the Analog Current output, with or without electrical barriers. If shielded cable is used, it
should be drained to dc ground at the auxiliary equipment.
2.1.3.7
Battery Backup
12-volt DC Battery Backup terminals are provided at terminal block TB3 on the rear of the analyzer chassis.
These terminals may be connected to a fixed 12 VDC power source to act as a back up in case mains power
has been lost. The circuit will detect loss of the mains power and the VDC battery backup will maintain
power to the analyzer.
Reminder
relay contacts are voltage-free. User devices controlled by the Model 5100E relay contacts
require additional power backup measures.
Connection to the battery backup is not required for normal operation of the analyzer. Be certain to match
the terminal pins against the terminal ID label on the top of the analyzer chassis.
