6. IN-PROCESS OPERATION
6.3 Simulation Function
The AXF has a simulation function and it is possible to
conduct testing for the downstream function blocks or
alarm processes. Following description is how to use
and how to set parameters in this function.
A SIMULATE_ENABLE switch is mounted in the
AXF amplifier (See Figure 6.3.1). This is to prevent
the accidental operation of this function. When the No
2 switch is ON, simulation function is enabled.
The [Target Mode] in each function block must be also
changed from [AUTO] to [O/S] before setting the
simulation parameters.
The simulation parameters in each function block
including alarm set as diagnosis in the AI block are
described below.
The SIMULATE_ENABLE switch (No 2 switch) and
the [Target Mode] in each function block must be
returned “OFF” / “AUTO” when the simulation
operation was finished.

WARNING
When opening the cover, wait for more than 10
minutes after turning off the power. Furthermore,
opening of the cover must also be carried out by
the trained personnel having knowledge of safety
standard.
IMPORTANT
• To preserve the safety, do not touch the
electrical circuit and cable except the
SIMULATE_ENABLE switch.
• Removing and installing cover are necessary
for the setting SIMULATE_ENABLE switch.
Perform removing and installing cover as
described in following Section of user’s manual.
Refer to Section 5.4.2.1 and Section 5.4.2.3 of
IM01E20D01-01E, or refer to Section 10.1.2.1
and Section 10.1.2.3 of IM01E20C02-01E.
