Electrical Hydraulic Control Unit
The direction of movement of the con-
vertible top (OPEN or CLOSE) is con-
trolled by 2 relays.
The cylinders are supplied with oil by a
hydraulic pump with 3 valves and with 2
directions of flow. A change in direction
by the hydraulic pump determines the
direction of movement of the pistons/
rams.
The hydraulic pump with a maximum of
200 bar is integrated into the hydraulic
control unit. The two relays and the 3
hydraulic valves for hydraulic control are also integrated into the hydraulic control unit.
The hydraulic control unit circuit is safeguarded with a slow-acting fuse rated at 50 amp.
fuse. To protect the hydraulic control unit, a "pump protection feature" is resident in con-
vertible top module (CVM).
