Telemark TT-6 Power Supply
This interlock insures that there is sufficient vacuum within the tank before the
source can be energized. This level of vacuum normally coincides with that
required for the energizing of vacuum gauge filaments and most units have
auxiliary contacts for this purpose. Their connection should be such that pins 3
and 11 of J102 are shorted when the filaments of the vacuum gauge are
energized.
Remote Emission Adjust - J103
The front panel mode switch must be set to
AUTO
to use the remote
voltage-control input.
Remote Emission Adjust is a differential input. Install the rate signal (zero to -1 O
volts) pin 3 and ground to pin 4 of J 103. The amplitude of this signal should
increase when it is desired to increase the evaporation rate.
The power supply can also be turned on and off remotely. This is accomplished
by connecting a normally-closed momentary switch across terminals 5 and 6 of
J103 and a normally-open switch across terminals 1 and 2. Depressing the
normally-open switch will turn the power supply on and depressing the normally
closed switch will turn it off. Logic level signals are provided to indicate the
operation of the power supply. A positive signal (12 or 24 volts selected by J1 O on
mother board) at pin 9 of J103 indicates that the power supply and filament
controller is energized. A signal at pin 7 is present when the power supply is in
cutback because of an arc. Pin 8 is a hard TTL low signal when HV/Emission is
engaged.
If the customer needs to use the remote input, but no external switches are
available or desired; move the motherboard jumper J11 to the
ON BYPASS
position and put an external jumper wire across J103 pins 5 and 6. (Note: If you
have Rev.Dor later mother board PCB, jumper J14 Off Bypass is provided to
eliminate external jumper.) This allows on/off operation from the manual
controller, while still switched to the AUTO mode, using the remote voltage-control
input.
