27) GONG FUNCTION
The GONG function is an entry warning triggered by the activation of the closing safety sensor (that is the sensor connected to the
terminal E.C.1, or to the terminal E.C.2) while the automatic door is being crossed.
To enable the GONG operation set the Multiple function F41m to option B on the digital selector ET-DSEL and insert the module UR24
into the connector J2 (OUT1) of the control unit ET‑LOGIC‑B.
If the module Ur24 is inserted into the connector J1 (OUT2) of the electronic control unit, set the multiple function F45m to option B.

02% to 100% = 1 second to 4 minutes.
ET-LOGIC- B CONTROL UNIT
Perform the following operations to activate the GONG function:
a) Use the module UR24 (refer to paragraph "UR24") and insert it into the connector J2-OUT 1 or J1-OUT2 of the control unit
ET‑LOGIC‑B.
b) Connect the entry ringer (GONG), taking the power supply and passing through the potential free contact at the terminals C-NO
of module UR24. The diagram above shows the electrical connection in the case of using a 24Vdc ringer, taking the power supply
directly from the terminals 21‑22 of the control unit ET‑LOGIC‑B.
c)
To activate the GONG function, use the digital selector ET-DSEL and set function F41m > option B (OUT1) or F45m > option B
(OUT2).
Now, each time the safety sensors are engaged during door closing, the GONG ringer activates for 2 seconds.
d) To change the waiting time elapsing from one GONG ringer activation to the next, when engaging the closing safety sensors, set
the parameter P19 on the digital selector ET-DSEL.
This waiting time is used to prevent the buzzer from sounding continuously in the case of flow of a high number of people.
This time is reset when the door is completely closed.
The table below provides some information about the waiting times according to the value set on P19.

e) Now the GONG function is definitely ON.
By crossing the automatic door and by engaging the closing safety sensors, the audible indication of the GONG will sound for 2
seconds; the GONG will then be inhibited for the waiting time set previously with P19.
Once the waiting time has expired, the GONG will be activated again for 2 seconds if the door is crossed, engaging the closing
safety sensors.
