2-60 Function COS Landis & Staefa Division

One COS,ACT entry has space for a maximum of 5 possible parameter states. But,

certain parameters can have up to 20 discrete states (values).

Therefore, an entered parameter value is taken as the START of a parameter value

range. This range then includes the following sequential possible parameter values up

to the next specified "Start Range", or to the last value which the relative parameter

can have.

All parameter values within a range take the attributes of their respective start value. If

an attribute is not specified (i.e. the first parameter value has not been assigned any

attributes) the next highest start value's attributes apply instead.

Parameters with analogue values (e.g. ME, PS) are handled as parameters with a single

discrete value. There is, therefore, only one single range and the prompt for "Colour" is

displayed immediately.

•

STEP2: Yellow/flashing (since the first range starts at STEP3 the preceding

parameter value take on these attributes).

•

Purge: Green/no flashing (the attributes of the second range apply).

•

Fire extract: Blue/flashing (by entering * at the fourth range this parameter value and

all following ones take the attributes of the fourth range).
