In the event you would like to supply the
controller
external drivers (see Fig. 3 and 4) with
compressed air, please make sure that:
The air pressure be within 1 and 6 bar, and however not higher than the input water pressure;
an air humidification system (with water or proper silicone lubricant) is mounted on the air line,
in order to prevent the driver internal seals from getting dry;
SIATA always recommends to supply the drivers with water. In this case it is necessary to use an
input filter to avoid impurities.
Please be particularly careful when installing the controller in environments that are not compliant
with the EN 50082-1 standard (electromagnetic compatibility).
5.3 – Maintenance
Mind to check the battery efficiency about every 12 months as follows:
Switch off the timer for at least 15 minutes.
The timer disconnected from the supply voltage, check the battery voltage using a multimeter. If
the measured voltage is less than 3,2 Vdc, replace the battery with the spare part code 867.
The following servicing operations
must always be performed when the controller is off power
.
In case of replacement of the electronic board only and each time you operate on the open case,
please avoid as much as possible touching the components and the welded parts with your hands,
above all in the microprocessor area, since possible electrostatic discharges could seriously damage
the controller.
Furthermore, we recommend not to place the electronic board on a metal surface, unless it is
properly isolated (a couple of paper sheets will be sufficient).
To store the electronic boards, please always use the anti-static envelopes that come with the
replacement kits.
Avoid the electronic board to come in contact with liquids. In case it happens, please dry it with an
air jet.
5.4 – Safety devices
The
controller
is provided with the following safety devices :
Safety and isolation transformer.
Safety electronic circuit against voltage peaks and disturbances.
