Intended use
The type of tubular drive described in these instructions is intended solely for the operation of vertical ZIP systems.
It may only be used in networked systems if all the individual drives are exactly synchronised and reach their limit positions at the
same time.
When mounting connection parts on the drive dia. 35 mm PXX/XX, only use screws EJOT Delta PT 40x12 WN 5454 Torx (9900 000
545 4).
For roller shutter applications, please use only the types of tubular drive designed for this purpose.
This type of tubular drive is designed for use in single systems (one drive per barrel).
The tubular drive must not be used in potentially explosive areas.
The connecting cable is not suitable for transporting the drive. Always carry the drive by the housing tube.
Other applications, uses and modifications are not permitted in order to protect the safety of the users and others, since these ac-
tions can impair the system’s safety and carry the risk of personal injury and property damage. The drive manufacturer does not
accept liability for damages or injury arising from such actions.
Always observe the information in these instructions when operating or repairing the system. The drive manufacturer does not ac-
cept liability for damage or injury resulting from improper usage.
Assembling and disassembling the plug-in connecting cable
Assembling the plug-in connecting cable
Insert the dead connecting cable into the drive head until the locating lug clicks into place in the drive. If necessary, use a suitable
flathead screwdriver to assist with insertion. Set the screwdriver into one of the two plug grooves provided for this purpose.

Assembling the drive
Attention
To connect the drive to the driven part, solely mechanical accessory components made by
the drive manufacturer from the current product catalogue may be used.
Prior to mounting, the fitter must ensure that the masonry and the system being motorised are sufficiently robust (drive torque plus
weight of the shading solution).
Caution
Electrical connections may only be carried out by a qualified electrician. Prior to assembly,
the power supply must be disconnected and secured. Please give the enclosed connection
information to the responsible electrical contractor.
These drives cannot be operated with conventional switching elements (switches, timers
and the like).

Calculate the space required at the side (M) by measuring the drive head (1) and wall
bracket (2). The clear dimension of the box (X) minus the space required at the side
(M) and idler (G) gives the length (L) of the barrel: L=X-M-G.
The space required at the side (M) varies depending on the combination of drive and
wall bracket.
Then mount the wall bracket and idler. Ensure that the barrel is aligned at right angles to the wall and that sufficient axial play is al-
lowed for the mounted system.
Undoing the mounting pin
When pushed in, the mounting pin (2) locks automatically. To undo the mounting pin
(2), push the tab washer (1) upwards and pull out the mounting pin (2).

The drive saves the limit position permanently once the upper limit position is reached 3 times in succession. Installation is then
complete. If the limit position is set above a point, this is stored permanently.
Setting the limit positions
The limit positions can only be set with the master transmitter. The shutter direction must
be correct. When setting the limit positions, the tubular drive runs in dead-man mode and
limit position status indicator. The lower limit position must always be set first. If the tubu-
lar drive switches off prematurely while opening or closing, due to an obstruction, the ob-
struction can be cleared by opening or closing the screen and removing the obstruction.
The desired limit position can be set by opening or closing again.
There are several ways to set the limit positions:
•Lower point to upper point
•Lower point to upper stop

Setting the limit positions with Auto-install (for ZIP applications with heavy end
strip)
For proper execution of the auto-install function, the necessary torque in the lower limit position must be at least 1/3 of the rated
torque of the tubular drive used.
Example:
Tubular drive 12Nm, barrel diameter 85mm (r= 0.0425m, no part of the shading solution is on the barrel when uncoiled). 1/3 of
the rated torque equals 4Nm; this means a minimum weight requirement of approx. 9.6kg in the lower limit position (shading solu-
tion + end strip) for this barrel.
Calculation:
4Nm / 0.0425m = 94N
94N / 9.81ms2 = 9.6kg
To set the limit positions with Auto-install, you need the "drive adapter for obstacle detec-
tion". If electrical power is removed from the drive during downward movement, the pro-
cess starts again from the beginning with the new downward movement.
Open as far as the permanent upper stop.
▻The tubular drive switches off automatically.
Run the fabric downwards until the drive switches off automatically and reverses,
while keeping the travel button pressed. The drive now moves one revolution upwards
and then down to the lower limit position that has been found, where it switches off.
Keep pressing the travel button until the drive clicks once, indicating that the lower
limit position that has been found has been saved.
Now move to the upper limit position twice, so that this is also permanently stored.
18

Obstacle detection (for ZIP applications with heavy end strip)
Caution
Obstacle detection is only active in conjunction with the "drive adapter for obstacle detec-
tion".
In addition, please note that the drive must be pushed in to the shaft as far as the band of
the thrust ring.
Use of the drive’s obstacle detection system as personal protection is not permitted. It has
been designed exclusively to protect the sun protection system from being damaged.
If the drive is correctly installed, it switches off when it detects obstructions or fabric faults and tries to run past the obstruction a
second time. If this fails, the drive switches off after the third attempt. Approx. 360° from the lower limit position, the drive interrupts
operation immediately following the first detection of an obstacle and makes no further attempt to continue.
The total number of attempts to complete a travel that has been started to the respective limit position is limited to 10 (distributed
over several obstruction locations).
If reversing is interrupted, a further drive command is only possible in the direction of reversing. Move the fabric without interrup-
tion until the tubular drive stops automatically. It is now possible to travel in both directions again.
