For installa on in Ex. situa on: refer to special condi ons in Sec on 5 of this manual. use only Ex. cer fied product
NOTE!
The Producer/Consumer model
•
The F783E 2.0 control module can be considered as having both Inputs and Outputs in both direc)ons, that is both
upstream and downstream from the module. To reduce confusion this document refers to the producer/consumer
model for informa)on transfer. In this model the F783E Module CONSUMES data from the control system or network
(i.e., controls the solenoid) and PRODUCES data for the control system (sends the state of the posi)on switches back to
the control system).
•
In this respect the control of the solenoid is considered as an Output and the feedback from the switches is considered
an Input. The connec)ons between the control system and the module are agnos)c, and ignored.
1 output via 2-pin header, normally suppled with a cable set with latching plug both ends to suit pilot valve
Outputs:
Two clean switch inputs from 3-wire induc)ve proximity switches, one each for the open and closed posi)on.
DC Inputs:
Two load derived switch inputs from 2-wire induc)ve proximity switches, one each for the open and closed
AC Inputs:
posi)on. There is a leakage current associated with these switches which must be allowed for when specifying PLC input
equipment. Maximum leakage at 24V is <1mA. When ON these switches will supply a minimum of 5mA.
11.3. Safety instruc ons
DANGER
!
Danger of explosion when used in explosive atmospheres (only in the event of a fault in zone 2)
Opening the control top in an explosive atmosphere is only allowed in a non-energised state
Use only cables and cable glands which have been approved for the respec)ve applica)on area and which have been installed
according to the respec)ve installa)on instruc)ons. Do not expose the device to any mechanical or thermal loads exceeding
that described in the opera)ng instruc)ons
WARNING
!
Risk of injury due to electric shock!
•
Before reaching into the system isolate the power supply when it is deemed the power supply could be capable of
causing injury from electric shock!
•
Observe applicable accident preven)on and safety regula)ons for electrical equipment!
Risk of injury from improper installa on!
•
Installa)on should only be carried out by qualified personnel and only with the appropriate tools
Risk of injury, product loss or damage from uninten onal ac va on of the system and uncontrolled opera on of the output!
•
Secure the system against uninten)onal ac)va)on
•
Following installa)on ensure a controlled restart
