7.5  Manual emergency actuation

CAUTION:

An injury hazard exists (crushing) with the use of emergency actuation with an Allen key.

 

Ö

When using the emergency actuation, make sure that there is sufficient space for persons and tools in the sur

-

roundings where movement takes place.

 

Ö

Observe the movement range of the eccentric shaft indicated by the marking on the housing (emergency actua-

tion 

bl

)!

 

Ö

O = Open

 

Ö

C = Close

bl

In the event of a failure of the electrical system, the element offers the option of being manually clamped or opened. For this purpose, the 

emergency actuation 

bl

 with hexagon socket is located on the front side of the eccentric shaft. An Allen key can be used here to move 

the element.

 

Ö

Turning counterclockwise = close

 

Ö

Turning clockwise = open

7.6  Checking operational readiness

After the element has been properly installed, check whether it is ready to be operated according to the following characteristics:

•  Check the ease of movement of the element by manually sliding the element perpendicular to the rail. 

 

Ö

In this process, make sure the sliding block 

2

 moves freely.

• 

Check the ease of movement of the element on the profile rail by manually sliding the rail carriage.

•  Check the clamping process by manually applying force against the closed element.

 

Ö

When doing so, the maximum holding force must not be exceeded.

•  Visually inspect the entire connecting cable to make sure it is properly installed.

• 

Check all fastening screws for the specified tightening torque. 

7.7  Removal

Removal is carried out in the reverse order of that described in Section 7.2.

8.  Technical data

The element has a product service life 

(B

10d

 value)

 of 500,000 cycles.

The 

B

10d

value 

is determined in accordance with ISO 19973-1 (dangerous failures with regard to the safety of machinery).

Error

1 = “high” = there is a signal = a voltage of 24 V is present.

0 = “low” = there is no signal = there is no voltage (0 V).

*) The clamp has an undefined status (not “OPEN” and/or “CLOSED”).

Example:

A signal failure may occur as a result of overvoltage (e.g. after closing or opening).

 

Ö

This means that there is no signal at the respective PIN (not “1” or “0”).

9.2  Behavior for “Voltage ON”

 

► From an undefined position: The element always tries to open first, then it executes the pending move command. A permanent 

signal is output in this status at the “Error” output (PIN 3).

 

► From a defined position:

The element stays in the position in front of “Voltage OFF”. The DIR signal has to change before the new move command can be 

executed.

9.3  Process charts

Signal for change of direction (DIR signal, PIN 1) after “Voltage OFF”

 

Ö

To achieve the desired status, a signal change is required when the operating voltage is switched on.

Signal (DIR signal, PIN 1) during opening

 

Ö

The element begins the opening process after a signal change from “Low to High” (0 V to 24 V).

Signal (DIR signal, PIN 1) during closing

 

Ö

The element begins the closing process after a signal change from “High to Low” (24 V to 0 V).

10.  Maintenance

The element is maintenance-free up to the number of cycles listed in Point 8 under the following conditions:

•  Adherence to the operating parameters
•  Proper installation

 

Even though the element is, as mentioned, maintenance-free, perform a regular visual inspection to check for corrosion, damage 

and contamination.

 

Clean the element as needed using a commercially available machine cleaning agent and then apply an anti-corrosion agent to the 

housing.

11.  Troubleshooting

INFORMATION:

For a precise and detailed overview of possible faults and corrective measures, please visit our website at

.

Zimmer Customer Service is available to provide you with assistance if you have any further questions.

12.  Transportation/storage/preservation

 

Transport and storage of the element must take place only using the original packaging or similar packaging.

 

If the element is already mounted on the superordinate machine unit, all power and installation connections must be checked prior to 

commissioning.

 

If the product is stored for an extended period, the following points are to be observed:

 

Ö

Keep the storage location as dust-free and dry as possible.

 

Ö

Package the product so that it is protected against corrosion.

 

Clean all components. There must be no soiling left on the components.

 

Apply corrosion protection in the correct manner.

 

► There must be a transport lock present between the contact profiles.

13.  Decommissioning and disposal

INFORMATION:

When the element reaches the end of its service life, the element can be disposed of. Completely disconnect the element 
from the power supply. When disposing of it, observe the locally applicable environmental regulations and codes and 
regulations for disposal.
