be defined via the Monitoring group. The green LED at the front panel turns off.
The
INHIBIT active time (LOW potential) must be at least 100 ms! When the INHIBIT is no longer active (TTL-HIGH potential
or not connected), the INHIBIT flag must be reset before the voltage can be switched ON again.
4.2.1 Logic / Signal Level Standard
The INHIBIT - signal has negative logic, which means it is LOW-active. When applying a TTL-low-level on INHIBIT input the
signal will be rated as ACTIVE, the high voltage generation will be switched off.
(see chapter connectors and pin assignment)
Default state = state at non wired signal input: By applying of Pull-Up or Pull-Down resistors (approx. 10 kΩ) the Default-
State will be defined.
Case 1 - IU
INHIBIT: Default inactive (=> high voltage is generated):
=> signal input has HIGH - level => pull-up resistor after V
cc
Switch off the HV by applying 0V on signal input
Case 2 - ID
INHIBIT: Default active (=> high voltage is not been generated):
=> signal input has LOW - level => pull-down resistor after 0V
Switch on the HV by applying V
cc
on signal input
4.2.2 Logic / Signal Level Negated
The INHIBIT signal has positive logic, that means it is HIGH-active. By applying of TTL-High-Level on INHIBIT input the
signal will be rated as ACTIVE, the high voltage generation will be switched off.
Default-State = state at non wired signal input:
Case 3 - NID
INHIBIT: Default inactive (=>high voltage is generated):
=> Signal input as LOW - level => Pull-Down resistor after 0V
Switch off the HV by applying of V
cc
(5V) on signal input
Case 4 - NIU
INHIBIT: Default active (=>high voltage is not been generated):
=> Signal input has HIGH - level => Pull-Up resistor after V
cc
(5V)
Switch on the HV by applying of 0V on signal input
4.3 L – Lower output current (HP only)
The output current is limited to a lower value, e.g. 100 µA.
4.4 T10 – Lower temperature coefficient (HP only)
Improved temperature coefficient of 10ppm/K
