The change of the colon display (between unit Nos. 1 20 to unit Nos. 21 40) occurs automatically
every 10 seconds. (However the display does not change if there are no higher-number units connected.)
To change the display to the higher-number units before 10 seconds have passed,
press the (FLAP) button.
An 8-digit display is used for display of the compressor total operating time (in 1-hour units).
When the first 4 digits are displayed, the top dot of the colon is illuminated. (Figure (A))
When the last 4 digits are displayed, the colon dot is OFF. (Figure (B))
The display of the first 4 digits and last 4 digits changes automatically after 10 seconds.
The display can also be changed by pressing the (FLAP) button.
<Compressor total operating time>:
(A) and (B) are displayed alternately
(The example here (0000, 0062)
indicates 62 hours.)
