This key works in a sequential way, each time this key is pressed, the reading in
Display 1
located on the left-hand side will change. This will display seconds or the
number of frequency cycles in alternating current.
Each time this key is pressed the timer will reset to 0, allowing the operator to
perform the next test. If the timer is not reset, all the outputs and displays will
remain on hold and blocked.
This key allows the selection of the
Timer
whether it is internal or external. Each
time this key is pressed the selection will change from one to another. There are 2
optic LEDs associated with this key.
3.2.2. OPTIC INDICATORS AND DISPLAYS
3.2.2.1. Function mode indication
There are 6 green LEDs of 3 mm. When these are lit they indicate mode function the equipment
has. These LEDs are associated with the
Mode
key.
a) START Mode indicators
These 2 LEDs indicate the start mode of the
Timer
in relation to the output
control ON/OFF and to the
2
nd
Value Step
press key. These 2 LEDs are 3 mm
and green. Only one can be used at the same time.
When the upper LED is lit, it indicates that the
Timer
will start when the output control is
activated (ON) or when there is a
Step to 2
nd
Value
. When this LED is flashing it indicates
that the
Timer
is in BUS mode, meaning that it will start when there is a positive event in the
BUS.
When the lower LED is lit, it indicates that the
Timer
will start when the output control is
deactivated (OFF) or when a
Step to 2
nd
Value
is deactivated. When this LED is flashing it
indicates that the
Timer
is in BUS mode, meaning that it will start when there is a negative
event in the BUS.
b) STOP Mode indicators
These 2 LEDs indicate the stop mode of the
Timer
in relation to the
Monitor
state. These 2 LEDs are 3 mm and green. Only one can be active at the same
time.
When the upper LED is lit, it indicates that the
Timer
will stop when the
Signal Monitor
is
activated. When this LED is flashing it indicates that the
Timer
is in BUS mode, meaning
that the
Timer
will stop when there is a positive event in the BUS.
When the lower LED is lit, it indicates that the Timer will stop when the
Signal Monitor
is
deactivated. When this LED is flashing it indicates that the
Timer
is in BUS mode,
meaning that the
Timer
will stop when there is a negative event in the BUS.
