3. HOLD-Function
The HOLD input responds for alternating and direct voltages between 12 V to 230 V.
During the elevator travel the measured loads can heavily fluctuate (friction in the rails
etc.). As long as a voltage (e. g. the travel signal) between 12 to 230 V is applied at the
HOLD input the alarm output through the alarm relays does not take place. If during an
elevator ride a signal is presented to the HOLD input or if no signal is presented when
the elevator is at standstill, the system automatically carries out a compensation of the
rope weight in case of elevators with multiple suspensions as well as a compensation of
the weight of a possibly existing compensation chain.
Slack Rope Alarm
There is a possibility to create negative switching thresholds by setting the first digit to
minus. Slack rope situations can be detected because the measured weight is below the
weight of the car.
4. How to Access a Parameter
The unit 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:
The unit 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.
