STP-ND
Note: Connect the motor drive power source between terminals D and G and the clutch operating power
source between terminals B and G. In this case, be sure that both power sources are one and the
same and the power source to be connected to terminal G is of the same phase.
STP-NR
Note: The Electrical Presetting type is not
provided with an operation indicator.
Precautions
Connection
Connecting the Power Supply
Power supply is connected separately for the motor and the clutch.
Connect the motor drive power supply across terminals 4 and 7 and
connect the clutch operation power supply across terminals 2 and 7.
Power supplied for both of these must be from the same power
source and the same phase must be connected to terminal 7. For
STP-R models, used the voltage applied for the clutch power supply
for resetting. Do not apply power continuously for both the motor
and clutch power supplies for extended periods of time.
STP-NH
STP-N2
Connecting Instantaneous Contact Circuit
Socket terminals 1 and 3 are for an instantaneous contact circuit
and are normally open. Terminal 1 is internally connected to termi-
nal 2 to connect power. The same phase must be used for both ter-
minal 2 and for terminals 1 and 3. The controlled load must therefore
be connected to the same phase of power as the power supply con-
nected across terminals 3 and 7. The instantaneous contact circuit
for terminals 1 and 3 can be used as a self-holding circuit for the tim-
er. This circuit, however, is electrically independent of the operation
power circuits for STP-NH and STP-ND.
Setting the Operating Time
Do not turn the adjustment for the operating time past the range on
the scale. If the clutch does not release then current is applied to the
clutch coil when using a power reset, the moving needle will not
move with the setting needle when the set time is increased (i.e.,
when the setting needle is turned clockwise).
