The next relay can be selected. Note that (Z9A + Z10A) could have been entered as zone
range ZR9:10(1)A.
Entering an NA Operand in a logic equation
To enter an NA operand, do the following:
1.
Select NA with the
█
in the bottom line and press "ENTER".
2.
Select the first token in the "RESET" group with the cursor keys and enter it.
3.
Select the next token in the "RESET" group and enter it (the comma will
automatically be inserted when this token is entered).
4.
When all the "RESET" tokens are entered, press one of the Operator keys ("AND",
"OR", etc) then enter the "SET" tokens (on the right side of the ;).
5.
Select the desired tokens with the cursor keys.
6.
When all the "SET" tokens are entered, press "AND", "OR", "XOR" or "NOT" to exit
from NA. If the NA is the last token in an equation and the operand just entered is
not required, press "DELETE".
NOTES:
1. A logic equation or another NA token cannot be entered directly as an NA operand.
An intermediate variable can be used to achieve the same effect.
7.4 OUTPUTS & ANCILLARY RELAYS
7.4.1 GENERAL
The Ancillary relays (Anc 1, 2, 3) on the MAF/PSU all have the option of supervision (i.e.,
checking the wiring from the relay to its load to see that it is not "short" or "open" circuited).
The supervision also includes a "confirmation" function, i.e., it expects to "see" a different
state after a relay has been activated. If an incorrect state is "seen" by the supervision,
before or after relay activation, then a "fault" is signalled for that relay. Supervision in the
activated state
can be disabled for “load” mode if it is not required, for example when the
relay switches the load to 0V.
For each relay, the supervision can be disabled if not required, mapped to the MAF, and
made latching or non-latching. Anc 1 and 2 relays can be programmed for two different
modes of supervision - door holder or load mode. All relays can be made individually non-
isolatable (prevents an operator from isolating them) and non-testable (prevents an operator
from isolating them).
