Output circuit troubles and corrective actions (continued).
Condition
Cause
Corrective actions
The load off
response time
is long.
y
Over current at off state [The large solenoid current
fluidic load (L/R is large) such as is directly driven with
the transistor output.
y
The off response time can be delayed by one or
more second as some loads make the current flow
across the diode at the off time of the transistor
output.
y
Insert a small L/R magnetic contact and drive the load
using the same contact.
Output
transistor is
destroyed.
Surge current of the white lamp
A surge current of 10 times or more when turned on.
y
To suppress the surge current make the dark current
of 1/3 to 1/5 rated current flow.
