Note that you may only change
>Com.G@te<
[46] when the temperature control unit is turned off.
In the category “Interfaces” you can change the settings of each function such as PoKo, analog
interface and RS232/RS485.
You may order >Com.G@te< [46] with Order No. 6915. You can extend an existing >Com.G@te<
[46] via a connecting cable (Order No. 16160).
6.3.1 Jack LEVEL (Com.G@te® external only)
For level monitoring in the >Sight glass< [23].
This connection enables you to connect an external float switch (Order No. 6152), which is posi-
tioned in the >Sight glass< [23], for monitoring the level of your externally closed application. Acti-
vation via a potential-free contact.
The interface is specified as a digital input. Do not apply voltage or current.
Pin Description
1 Level test (bypass via contact 2 → “absence”)
2 Level – (GND)
3 Level + (normally open contact)
6.3.2 Connector POKO (floating contact) alarm
Information on the interface can be found on page 63 in Section »Connector POKO (floating con-
tact) alarm« .
6.3.3 Jack AIF Reg-E-Prog
The analog interface has a programmable input channel and 3 output channels.
The analog interface of Com.G@te® is programmed in the category “Interfaces”.
