EV91D - SLAVE
GENERIC OUTPUT
MODULE
RELAY OPERATION PROGRAMS
All these four relays can be congured to operate in
the three different modes listed below:
- AUTOMATIC The relay works automatically accord-
ing to the time programming set by the user.
- ALWAYS OPEN The relay contact is always kept
open.
- ALWAYS CLOSED The relay contact is always kept
closed.
TIME PROGRAMMING
All four outputs may be piloted to close according to
the time programming of three time bands for each
day of the week, when the related relay has been pro-
grammed in AUTOMATIC mode.
In the period between the three ON and the three
OFF times, the output is piloted to close whereas out
of this period it is piloted to open. If one of the three
time bands is excluded (to do this press the PLUS
and MINUS keys of the remote keyboard to highlight
the dashes --,--) the output is piloted to open.
USE
The EV91D module is suitable to be used on all
plants where it is necessary to start pumps, generic
motors, mixing valves, etc. It is therefore suitable to
be used on heating and/or air-conditioning plants,
greenhouses, swimming pools and industrial plants.
OPERATION
The EV91D module features four relays, each of
which may be associated with an operation program
and a weekly time programming.

INSTALLATION
INSTALLING THE CONTROL UNIT
Mount the device onto the DIN rail inside a panel in
order to provide suitable protection. Removable ter-
minal boards facilitate wiring and replacement. Con-
necting leads to the control unit must have a section
of at least 1 mm2 and a length of 1000 metres.
CONNECTION TO THE FANBUS
Connect the EV91D control unit to the Master EV90
through the FANBUS. Bear in mind that the bus has
low voltage and it is not polarised, terminals can
therefore be inverted with each other without causing
malfunction.
CONTROL UNIT ADDRESS
The control units must be addressed through the
terminal board to work properly. The address of the
EV91D unit is made up of a high part that corresponds
to number “5”, and a low part that may take on a
value between “0” and “7”. The MASTER unit starts a
progressive search of SLAVES EV91D from address
“50” and it will stop if it gets no reply. It is therefore
necessary that connected slaves have different con-
secutive addresses starting from address “0”.
The diagrams below show how to set the low part of
the address through terminal board ‘A’ :
ADDRESS “50” ADDRESS “51” ADDRESS “52” ADDRESS “53”
ADDRESS “57”ADDRESS “56”ADDRESS “55”ADDRESS “54”
