Perry Electric E Series Installation

ELECTRONIC LEVEL REGULATORS
DIN RAIL installation
The lever regulators for conductive liquids are devices which
regulate minimum and maximum
cisterns etc. ,
The operating principle is based on control box detection of fluid
resistance of the level being controlled by means of special
probes immersed in the liquid itself, with the longest acting as
the common element. When the level of the liquid inside the
container or the well wets all three immersed probes, a relay is
activated and subsequently de activated only when the level
goes back down, no longer covering the lower probe.
SAFETY WARNINGS
Carefully read the instruction manual before using the product as it
provides important guidelines regarding safety, installation and
use. The instruction manual must be preserved with care for future
reference. he manufacturer reserves the right to introduce any T
technical and/or constructive changes deemed necessary, with no
prior notice.
The installation and electrical connection of the device must be
implemented only by a qualified electrician and in conformity
with current laws and regulations.
The manufacturer disclaims all responsibility for any product
use which does not comply with related environmental and/or
installation norms.
Disconnect the control panel electrical current before any device
operation.
NOTES REGARDING USE
If the device is used in the filling function, the system must be
equipped with an adequate too full.
In the case of wells with diameters up to 10 cm, position the probes so that there are no more than 2 m between the lowest and highest probes
(sufficient for pump protection). The probes can be set at a further distance for wells with larger diameters. There are no limits for tanks. These models
regulate liquids well for a resistance of up to 100 kOhm the use of these regulators allows extraordinary operating safety, as they are only slightly
sensitive to the conditions of humidity generally found in wells and tanks.
Aside from the above described performances, Series E (evolved) models also permit:
- setting of a delayed relay activation time from 0
- selection of the relay intervention mode (Filling/Emptying)
- Relay output with 2 change-over contacts in 3 DIN module version.
ALL MODELS ARE TROPICALISED, meaning they have been treated for continuous operation in conditions of elevated humidity and
temperature.
Application diagrams relative to the emptying and filling functions are shown, respectively, in Fig. 1 and Fig. 2.
Connection diagrams for the various models are shown in Fig. 3 - 4.
