5) Opening/Closing Speed Limit (ITEM No.19)
Opening/closing speed affects the thrust. Refer to Tables
5 – 6 and Figures 10 – 11 for checking required thrust
and attainable speed.
Acceleration or deceleration is not included in the speed.
Acceleration or deceleration respectively requires ap-
prox. 0 to 2 sec.; takes longer with faster speed.

Speed [V] achieved by Speed Scales [A] other than mentioned
above can be approximately calculated by the following equa-
tion:
Speed [V] = 0.106 × Speed Scale [A] + 0.323, where 2 ≤ A ≤ 50

6) Deadband (ITEM No.20)
Deadband is adjustable as % of the maximum stroke
within 0.1 to 5%.
7) Restart Limiting Timer (ITEM No.21)
The timer is provided to protect the motor from overheat-
ing, preventing it from restarting for a certain interval
once the motor has been stopped within deadband.
When the high temperature protection is activated in a
high temperature ambient, adjust the timer to a longer
interval.
Adjustable range is within 0 to 30 sec.
MANUAL OPERATION
■
WHEN POWER IS AVAILABLE TO SUPPLY TO PSN
1) Turn on the power supply.
2) Turn on the SW-8 to put the PSN into the local calibra-
tion mode.
3) Use UP/DOWN buttons to manually operate the PSN.
4) Turn off the SW-8 after turning off the power supply.
■
USING THE MANUAL OPERATION STEM
1) Be sure that the power supply is removed.
2) The output stem is designed to go up when the manual
operation stem turns clockwise (seen from the operation
stem side). Turn the handle with a torque under 1 N·m
or 0.74 ft·lb (1.5 N·m or 1.48 ft·lb for PSN3) in checking
the stem position with the indicator.
3) The output stem moves by 10 mm per approx. 24 turns
(approx. 25 turns for PSN3) of the manual operation
stem.
4) When the operation is completed, be sure to remove the
handle and cover the stem with a rubber cap.
5) Be sure that the handle is not attached before turning on
the power supply.
6) Use a 8-mm spanner as a handle.
