Description

General

The Output amplifier OPA 8500 amplifies TV/QAM/FM signals, which are present on the
inputs of the OPA 8500. The OPA 8500 supplies the following coaxial or optical
downstream distribution system with the amplified signals.
The RF-output, RF-inputs and two RF-monitoring outputs operate in the frequency
range 47 ... 862 MHz. The OPA 8500 is built with two parallel hybrids. Two equivalent
mains connections are available via the rear-panel.

The OPA 8500 is used in a combining network. The combining network consists of the
following functional groups:

RF-combiner RFC 8500/5

l

RF-combiner RFC 8500/4

l

1 HU Mounting frame MIO 8500 (for maximal 3 RF-combiners)

l

Output amplifier OPA 8500

l

The OPA 8500 has 10 RF-inputs and one RF-ouptut. The RF-inputs are meant:

for TV- or QAM-signals (4 RF-inputs)

l

for FM-signals (4 RF-inputs)

l

for pilot frequency signals or wobbler (2 RF-inputs)

Cooling The SAI 8500 is cooled by convection.

Power supply

The OPA 8500 can be operated with the following mains voltages:

l

115 VAC

l

230 VAC

The power supply is of redundant design. For back-up purposes there are two mains
connectors available on the rear-panel. The OPA 8500 can be integrated into a back-up
supply system.

ATTENTION: Before operation make sure that the mains voltage matches the

supply voltage indicated on the device.

The mains fuse is located beside the mains socket. The OPA 8500 does not have a
mains switch. To disconnect the OPA 8500 from the mains, both mains plugs must be
pulled out of the device. Both mains voltages (mains 1, mains 2) can be monitored
through alarm messages.

Start-up

Putting into operation

ATTENTION: Operating work must be carried out by staff with RF-knowledge.

ATTENTION: If the device is steamed up after unpacking, it must be acclimatized

at least one hour before starting operation.

ATTENTION: During operation the vents must not be covered. When mounting

the device in a rack take care that there is a gap of at least 1HU
between the devices.

NOTE: When building in the device in a rack use rails or any other suitable

mount.

Procedure

NOTE: Before operation read the chapter ”Menu operation”.

1. Check if the supply voltage shown beside the mains socket matches the mains
voltage.

ACHTUNG: A wrong mains voltage may cause a defect in the device.

Therefore check the mains voltage before connecting the module to
the mains.
Delivery state: 230V~ (Changing to 115V~ see maintenance/change
of the mains voltage)

2. Slide in the OPA 8500 into the intended place in the 19" rack.

3. Fix the module with the 4 screws on the front-panel.

4. Connect the signal cabling.

5. Connect the OPA 8500 to the mains ( boot procedure starts).

6. Adjust the contrast of the LC-display (see menu operation ”display / contrast”)

7. Check the LED´s on the front-panel.

l

LED “ f ” does not light up

l

LED “OUT” lights up

8. Set the desired warning- and alarm thresholds for the displayed values.

Operation

Cursor keys The OPA 8500 is operated via the key pad on the front-panel. With the cursor keys “↑”

and “↓” you can select the desired menu item. With the cursor key “→” you enter the
desired menu. With the cursor keys “↑” and “↓” you can select the desired function in

the sub-menu.

ESC-key With the ESC-key you can move one level up in the menu tree.

ENTER-key With the ENTER-key you select a setting or a measured value, and confirm an entry.

Change settings

Select the value to be changed by pressing the ENTER-key.

Position the cursor with the keys “←” resp. “→” and set the desired value with the

l

keys “↑” and “↓”.

You can exit a configuration menu in the following way:

to confirm the entry press the ENTER-key

l

to cancel the entry press the ESC-key

l

l to exit the menu press the ESC or cursor key “←”

If a value is changed, a range-window shows up on the display. The
vertical line represents the value currently set.

When changing the value, the line is moving along in the range-window. If the possible
adjustment range is left, it is indicated by an arrow. Input values outside the valid range
are not accepted. An error message “value out of range !” is displayed.

On the right margin of the display an information bar is located. The following displays
are present:

Arrow to the top resp. to the bottom : further menus can be selected by
using the cursor keys.

Arrow to the right: by using the “→”-key a submenu can be selected.

Alarm and warning messages

By pressing the ENTER-key an alarm- and warning threshold value for a status
message or displayed value can be defined.

With the cursor keys “←” and “→” the text can be scrolled through. With the keys “↑”
and “↓” the following settings can be changed:

selection between alarm and warning message

l

selection of the message state: “EN” enables the message, “dis” disables the

l

message.
selection of condition for status indication (e.g. “if locked” or “if not locked”)

l

for display values the thresholds (upper limit, lower limit) can be selected and

l

changed. (see change settings)

Confirmation of the entries with the ENTER-key.

Menu operation

Display of an “E” : the currently selected setting can be
edited/changed.

Display of an “L” : for the currently selected status resp. value a
warning- or alarm-messge can be defined.

Password protection

Menu “Change password” You can provide the OPA 8500 with a password protection. At delivery the password is

“0000". Password query is suppressed with this password. To protect the OPA 8500
from unauthorized use you have to change the password.
However, query of the parameters and settings is possible at all times.
After entering the password (query) all settings can be changed without
restrictions. If no key is pressed during a period of 30 minutes, the device changes back
into the protected mode.
Repeated entry of the current password in the menu or the entry of a new password
causes the device to change immediately to protected mode.

NOTE: Write down the changed password. In case of loosing your

password contact the next service center.

Changing the mains fuse

ATTENTION: Danger of electric shock!

Disconnect the OPA 8500 from mains before changing the fuse
(both mains connectors)!

Procedure 1. Disconnect the OPA 8500 from the mains.

2. The fuse holder is located beside the mains socket. (see chapter “start-up /
interfaces and operating elements”) Open the bayonet lock of the fuse holder
with a screw driver.

3. Replace the defective fuse (5x20 mm). The fuses have, depending on the mains
voltage, the following values:

230 V mains connection 0,8 AT

l

115 V mains connection 1,6 AT

Maintenance

Changing the battery

ATTENTION: Danger of electric shocks !

Disconnect the OPA 8500 from the mains before
changing the battery !

WARNING: Improper change of the battery may cause an explosion.

Replacement only by the same or an equivalent type
recommended by the manufacturer !

ATTENTION: Lithium batteries must not be disposed of as domestic waste !

Send the used batteries back to the manufacturer or
supplier. Address of the manufacturer of the battery:

Firma RENATA AG
Kreuzenstr. 30
CH-4452 Itingen

NOTE: The data in the ERROR history and the note entries (when using

in the network ) get lost when the battery is changed.
