3. Alarm Relays
AL-1 (change-over contact)
Changes state as soon as the load limit adjusted by AL-1 is exceeded.
AL-2 (change-over contact)
Changes state as soon as the load limit adjusted by AL-2 is exceeded.
AL-O (change-over contact)
Changes state as soon as the load limit adjusted by AL-3 is exceeded.
4. HOLD-Function
The HOLD-input responds to alternating and direct voltages between 12V and 230V.
Due to friction at the guide rails etc., loads measured during travelling might heavily
fluctuate. This will prevent the alarm from putting out any alarm as long as the HOLD-
input is supplied with voltage (e.g. travelling signal).
5. How to Access a Parameter
Weightwatcher light is provided with a menu offering access to the adjustable
parameters.
This key is pressed to browse through the menu items. After selecting a menu
item, it is used to navigate through the sub-menu. For parameters, it helps you set the
parameter-value desired.
This key is pressed to select a menu item displayed, or to apply the value set for a
parameter.
This key is pressed to quit the current menu item or parameter without applying
the set value. By repeatedly pressing this button, you will return to displaying the
current total load in the car.

Attention:
Weightwatcher light AE16 automatically returns to its home-position displaying the
current total load in the car, and will do that after one minute without any push of a
button, regardless of which menu-item had been selected beforehand.
After ten minutes without any push of a button it changes into the energy-saving mode,
i.e. the display goes off for being reactivated by the next push of a button.
6. How to Adjust a Parameter
1.) Press button to navigate through the parameters until the one to be
adjusted is displayed.
2.) Press button to select this parameter.
3.) Press button to navigate to the value desired for the currently flashing digit.
Press button to change to the next digit.
4.) After setting the last digit, press button again. After that the whole figure will
be flashing.
5.) Press button once more to apply the adjusted parameter.

8. How to Adjust the Number of Rope Sensors
a) By navigate to menu-item rCnt (rope count) and select it
by pressing .
b) Follow the instructions of item 6 „How To Adjust A Parameter“ and adjust the
correct number of rope-sensors.
c) It is possible at any time to quit this menu-item by pressing .
Attention:
It is inevitable to adjust the true number of rope-sensors as otherwise AE16 light would
trace missing sensors and switch to the error-mode by activating all alarm-relays.
9. How to Calibrate the Load Measuring
Leaving the pre-adjusted menu-item Units unchanged means that the loads
are to be entered in terms of percent of the nominal load, such as for example
100% for full load and 105% for overload.
Take the following steps to calibrate the evaluation unit of WeightWatcher light:
1. Mount the rope-sensors LS-light to the ropes.
2. Connect sensors to evaluation unit AE16light
3. Connect AE16light to a power supply ranging between 12V and 28V DC
4. Calibrate the evaluation unit AE16 both under full load and zero-load conditions.
a. How to Calibrate Zero Load
Purpose of this function is to compensate the weight of the empty cabin.
Take the following steps:
i. By navigate to menu-item CALib and select it by pressing
. Then navigate by to menu-item ZEroC and select it
by pressing . The standard value (refer to Units) is
000*o (0% load, i.e. empty cabin). As soon as you will have
adjusted the last digit, the whole figure will be flashing.

ii. Apply it by pressing . After that a countdown will be running
from 99999 to 00000. At 00000 the current weight of the
car will be measured. It goes without saying that at that moment
there must not be anything in the cabin or on the car roof that
does not belong there under normal operation conditions (tools!),
and that there must not stay any person in the cabin or on the car
roof in order not to warp the zero load parameter.
b. How to Adjust Full load
Take the following steps:
i. By navigate to menu-item CALib and select it by pressing
. Then navigate by to menu-item LoadC and select it
by pressing . After that adjust on the display an arbitrary load
to be loaded into the cabin. Unless you changed the standard of
menu-item Units enter this load in terms of a percentage of the
nominal load, i.e. 100% (100*o), if you are loading the nominal
load, or 75% (075*o) if you are going to load ¾ of the nominal
load only. As soon as you will have adjusted the last digit, the
whole figure will be flashing.
ii. Apply it by pressing . After that a countdown will be running
from 99999 to 00000. At 00000 the current weight of the
car including load will be measured. It goes without saying that at
that moment there must not be anything additional in the cabin or
on the car that does not belong there under normal operation
conditions (tools!), and that there must not stay any person in the
cabin or on the car roof in order not to warp the full load
parameter.
iii. As from now on calibration of the rope-sensors is completed and
in effect.

10. Alarm Limits
Alarm limit: a designation that corresponds to the load limit in the cabin, which – if
exceeded – will change the state of the alarm relay. After changing the state of the
alarm-relay, the corresponding status-LED will be luminating.
AL-1 (freely programmable load)
Changes its state, if the load limit adjusted by parameter AL-1 is exceeded.
AL-2 (freely programmable load)
Changes its state, if the load limit adjusted by parameter AL-2 is exceeded.
AL-3 (freely programmable load)
Changes its state, if the load limit adjusted by parameter AL-3 is exceeded.
How to Adjust the Alarm Limits:
1. By navigate to menu-item ALArm and then press .
2. Now – in the same manner – navigate to the alarm limit to be adjusted (AL-1,
AL-2 or AL-3) and select it by pressing .
3. By navigate to the desired value of the currently flashing digit and select it
by pressing . This will at the same time make the next digit flash.
4. After having adjusted the last digit and accordingly pressed , the whole
figure will be flashing.
5. Press once more to apply the parameter.
6. You can quit this menu-item at any time by pressing .
Attention:
Unless you changed the standard setting of menu-item Units, the alarm
limits are to be adjusted in terms of percentage, i.e. 100% for full load and 105%
for overload.
