Label ETERNA 90 - Gong Function Operation; Activating the Entry Warning Gong

55
27) GONG FUNCTION
The GONG function is a entry warning triggered by the activation of the closing safety sensor (that is the sensor connected to the E.C.1
terminal, or to the E.C.2 terminal) while the automatic door is being crossed.
To enable the GONG operation set the F41m function option B on the ET-DSEL digital programmer if UR24 module into the J2 (OUT1)
connector of the ET-LOGIC-B control unit.
If UR24 module into the J1 (OUT2) connector of the control unit set F45m function --> option B.
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.
Perform the following operations to activate the GONG function:
a) Use the UR24 module (please refer to paragraph 24) and insert it into the J2-OUT 1 or J1-OUT2 connector of the ET-LOGIC-B control
unit.
b) Connect the entry warning buzzer (GONG) by connecting the power supply to the voltage-free contact at terminals C-NO of the UR24
module. The diagram above illustrates the electrical connection in the case a 24Vdc supply is used, by taking the power supply directly
from terminals 21-22 of the ET-LOGIC-B control unit.
c) To activate the GONG function use the ET-DSEL digital programmer and set function F41m --> option B (OUT1) or F45m --> option B
(OUT2).
At this point each time that the safety sensors are operated when closing the door the GONG will sound for 2 seconds.
d) To change the waiting time elapsing from when the GONG buzzer is activated to the next time it is activated, engaging the closing safety
sensors, act on the P19 parameter on the ET-DSEL digital programmer.
This waiting time is used to prevent the buzzer from sounding continuously in the case of the passage 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 set value of P19.
