Section 2 - Analogue Primary Options
OPTION E, EV, F, FV, xEV, xFV
The Analogue primary option is a factory fitted option board which provides the following functions:
1) Warning the AC input has been lost or that the converter has overheated.
2) Global inhibit / enable (Global meaning the option inhibits/enables all modules or outputs at the same time).
3) 5V auxiliary supply (5V being present when AC is applied and regardless of inhibit/enable status).
The option board occupies a position to the left of slot 5 as shown:
Pin No.
Function
1
AC fail and over temperature warning, C
2
AC fail and over temperature warning, E
3
0V of auxiliary supply and 0V "reference" or "return" for global inhibit / enable.
4
5V auxiliary supply
5
Global inhibit/enable logic "0" input
6
Global inhibit/enable logic "1" input
INHIBIT OR ENABLE.
One of two options are available (
required option must be specified at time of ordering
) : Inhibit or Enable.
Both are TTL compatible.
They are physically the same but with different functionality.
Option specified = "INHIBIT"
All outputs normally "ON" (even if not
connected)
PIN 5 taken to 0V-0.8V will turn
outputs OFF.
PIN 6 to be taken to 2-5V will turn
outputs OFF.
Option specified = "ENABLE"
All outputs normally "OFF" (even if
not connected)
PIN 5 taken to 0V-0.8V will turn
outputs ON.
PIN 6 to be taken 2-5V will turn
outputs ON.
All voltages are with respect to auxiliary 0Volts (PIN3 ). Both Pin 5 and Pin 6 will draw almost no current being the input to a
comparator with suitable hysteresis.
