CIRCUIT DESCRIPTION
5. CK-50 Plunger Specifications
5-1. Statuses which cause unlocking
1. Unlocking occurs when ACC is switched from
ON to OFF while the panel is attached.
2. Unlocking occurs when the lever is moved up-
ward while the panel is attached and ACC is ON.
3. Unlocking occurs when the panel is attache
while ACC is OFF.
5-2. Statuses which do not cause unlocking
1. While the panel is detached.
2. For 10 seconds after the set is installed or raset.
3. For 10 seconds after the completion of unlock-
ing.
5-3. Reason of item 2 of "Status which do not cause
unlocking"
.
:
When the microcomputer is reset while the panel is
attached, the microprocomputer program starts as-
suming that the panel is not attached, so unlocking
would occur because it detects that the panel is at-
tached. If this operation takes place every 10 seconds,
the plunger would be destroyed due to excessive un-
locking.
Similarly, if the set is detached in 10 seconds after
moving the detaching lever up then it is attached im-
mediately and this operation is repeated, the plunger
would be damaged because the microcomputer is re-
set every time the set is attached.
5-4. Unlocking timing
Unlocking shall continue for 10 seconds, and a hold
period of 10 seconds must be provided after the com-
pletion of unlocking.
