If you reconfigure the equipment for a line voltage other than the one marked on the serial
label and the mains filter of the power supply then you should change the marking on the
serial label and the mains filter to state the new line voltage.
If incorrect heater voltage is selected, damage to the probe may occur. For HPS voltage
selection jumper, refer to Figure 2-15.
Figure 2-5. Power Supply Board Jumper Configuration
b. Electrical Connections
1. The IFT can be configured for 100,
120, 220, or 240 line voltages. For 120
Vac usage, install JM8, JM7, and JM1.
For 220 Vac usage, install jumpers
JM6, JM5, JM2 (refer to Figure 2-5 and
Figure 2-6).
If you reconfigure the equipment for a
line voltage other than the one marked
on the serial label and the mains filter
of the power supply you should
change the marking on the serial label
and the mains filter to state the new
line voltage.
2. The IFT can be configured to connect
directly to a probe or to an optional
HPS. The electrical connections for a
non-HPS equipped system should be
made as described in the electrical in-
stallation diagram, Figure 2-7.
Do not install jumper JM6 on the mi-
croprocessor board, or JM1 on the in-
terconnect board, if an HPS is
installed in the system. This will result
in system failure.
3. The IFT must have JM6 on the micro-
processor board (Figure 2-8 and Figure
2-9) and JM1 on the interconnect
board (Figure 2-10 and Figure 2-11)
installed if an HPS is not installed in
the system.
4. If an MPS is not used in the system,
wire jumper between CAL RET and NO
GAS must be installed on the intercon-
nect board. Remove wire jumper if
MPS is installed in the system. Refer to
Figure 2-7, note 6.
5. The power cable should comply with
the safety regulations in the user's
country and should not be smaller than
16 gauge, 3 amp.
