Transistor Output
The transistor output of TC-Pro is insulated from the
internal circuitry by a photocoupler, so the transistor
output can be used as both NPN and PNP output.
The diode connected to the collector of the output
transistor is used to absorb inverted voltage that is
generated when an inductive load is connected to
TC- Pro.

Changing the set values
When changing the set value during a timing
operation, the output will turn ON if the set value
is changed as follows because of the use of a
constant read-in system:
Elapsed time(up) mode: present value≥set value
Remaining time(DOWN) mode: elapsing time≥ set
value(the present value is set to 0)
Note: when in the remaining time mode, the amount
the set value is changed is added to or subtracted
from the present value.
Connection
Make sure that wiring is correct.
Mounting
Tighten two mounting screws on the adapter.
Tighten them alternately, a little at a time, so as to
keep them at an equal tightness.
TC-Pro panel surface is water-resistant. In
order to prevent the internal circuit from water
penetration through the space between the TC-
Pro and operating panel, attach a waterproof
packing between TC-Pro and installation panel
and secure the waterproof packing with the BK-62
flush-mounting adapter.
Operation environment
Use the product within the rating specified for
submerging in water and exposure to oil.
Do not use in location affected by excessive
vibration or shock
Do not use the product in locations subject to
dust, corrosive gases, or direct sunlight.
Separate the input signal devices, input signal
cables, and the product from the source of
noise or high-tension cables producing noise.
Separate the product from the source of
static electricity when using the product in an
environment where a large amount of static
electricity is produced (e.g. forming compounds,
powders, or fluid materials being transported by
pipe).
Organic solvents (such as paint thinner), as well
as very acidic or basic solutions might damage
the outer casing of the TC-Pro.
Use the product within the rating specified for
temperature and humidity.
Do not use the product in locations where
condensation may occur due to high humidity
or where temperature changes are severe.
Store at the specified temperature. If
TC-Pro has been stored at a temperature of
less than -10
℃
, allow TC-Pro to stand at room
temperature for at least 3 hours before use.
Note: auxiliary relay (e.g. MY relay)
Insulation
There is basic insulation between power supply and
output terminals.
Input and output terminals are connected to devices
without exposed charged parts.
Input and output terminals are connected to
devices with basic insulation that is suitable for the
maximum operating voltage.
