rate of 3 per minute for 1.5 minutes.
(1)
The voltage from connector 2J2-8 to 2J2-9 shall remain
at 6.5 1Vac.
(2)
The voltage from connector 2J2-17 to 2J2-18 shall
remain greater than 8Vdc.
h.
Repeat step g with a rate of -3 per minute for 1.5 minutes.
4.6.4.14.1.1 Switching Rate - The switching rate shall be checked as
follows.
(Note:
During steps b through d, the dc voltage may
temporarily become less than 1Vdc while the switching rate is applied.
The time at which this occurs shall not be recorded.)
a.
Set the controls on the controller and the electronic control
amplifier as follows:
