b.
When the applied signal goes inactive, the TRIGGER INPUT will disable. In this way, the
user can effectively “gate” a stream of trigger pulses and allow one or more to be received, as
determined by the user.
c.
This input can be used to “pick” a pulse or pulses from a series of trigger pulses presented to
the TRIGGER INPUT.
d.
This input must be used in conjunction with the TRIGGER INPUT BNC.
e.
This input can be set active-high or active-low by FUNCTION switch D. See “FUNCTION
Select” under GENERAL CHARACTERISTICS.

8.
115 VAC 60Hz. /230 VAC 50Hz
Input Module.
Mates with female IEC plug on supplied line cord. Includes the following additional functions:
a.
Power switch – “0” is off, “1” is on.
b.
Power fuses: 3AG, 0.5A, time lag (slo-blo) for 115 VAC 60Hz (2 required), 3AG, 0.25A,
time lag (slo-blo) for 230 VAC 50Hz (2 required). See “LINE FUSE REPLACEMENT”
instructions.
c.
Voltage change switchover block. See “VOLTAGE CHANGE” instructions.
d.
3Amp line filter. (Internal, not user accessible)
9.
AUX/GND/+5V
Auxiliary Terminal:
a.
A 3-pin pluggable terminal block connector.
b.
Both +5.0 VDC and Ground are available in addition to an AUX DELAY signal.
c.
The
VMM-T1
AUX output is now the DELAY timer output signal.
d.
An active-high pulse is delivered to this output equal to the length of the DELAY timer
setting. See “DELAY Out (AUX Pin 1)” under EXTERNAL OUTPUT
CHARACTERISTICS.
