West Control Solutions KS 800 Operating Instructions - Manual (Page 8)

Multi-Temperature-Controller KS 800
Several units: For mounting several units side by side, snap on the first unit to the rail and lock
only the side on which no other unit shall be mounted. Snap on the second unit like the first one,
approx. 2 cm beside the first unit and shift it sideways to connect it to the first unit (locking pins
click into position). Press down the second latch of the first unit only now.
The connectors on the instrumentside (board-toboard connector; type: AMP champ-050-connection)
are used only for CANBUS through-connection, i.e. one CANbus connection is sufficient for several
units mounted side by side.
Bus connectors: These connectors are not used with the KS 800 Profibus and RS485 versions. In
this case, each unit must be connected to the bus separately via the 9-pin sub-D-connectors.
If the KS 800 units are operated together with other P-Open components in a CANbus system, the
KS 800 units must be connected as last instruments at the left or the right end of the modules side
by side on a rail. Otherwise, the individual component cannot be addressed. (The "addressing line"
is interrupted by KS 800.)
3.2 Dismounting
For dismounting, the leads need not be disconnected.
Before removing, mark the upper parts of the connectors and the corresponding lower parts, becau-
se the terminals are protected by design against distortion but not against wrong polarity.
For releasing the upper part of a terminal, press the two red ejectors in a terminal row towards the
circuit board by means of a screwdriver, if necessary.
For releasing the unit from the mounting rail, draw the two side latches (1) forwards by approx.
5mm (latch released) and remove the unit from the mounting rail by tipping it down or up.
For replacing an "inner" one of several units mounted side by side, start releasing the latch (and the
latch of the following unit!) at the end of the row and shift the unit sideways. Repeat this procedure
until reaching the unit which must be replaced. When its locking pins are free on both sides, the unit
can be tipped down or up out of the mounting rail.
