Industrial products: STAGER (PILOT DISTIBUTOR) : TUYA electra double :

The pilot distributor (stager)  TUYA electra double

For double alternatly filter plants, within programmer.


TUYA electra double:

control the membrane chambers single effect with spring return. The pilot distributor has its inner programmer (it does not need a programmer or PLC).

Connection for six membrane chamber, six programmable phases pilot (5 phases of the regeneration).

Start rigeneration: volumetric, temprizzed,       with external signal (analyzer, pressure switch) or manually.
With daily inner clock

Outputs relais (n.o. / n.c.):

REL1: additional programme  no. 1 (activation before, during or after regeneration –  duration programmable)

REL2: second  additional programme no. 2 programmable (as above)

REL3: general alarm or dosing impulso (only with water meter)

REL4: exercise valve filter 1 (add solenoid valve) or a contact during the supply of the treated water and a contact during regeneration

REL5: exercise valve filter 2 (as above)

Analogic output:

4 – 20 mA: operation signal of the plant double filter and general alarm

Inputs (n.o.):

WM: lunch pulse water meter

IN1: Stop regeneration away (interrupt a current regeneration)

IN2: Start regeneration or Stop (block the beginning of a regeneration)

IN3: Opening/closing exercise valve away

Examples of use: close the treated water’s supply in force, in case of storage tank full

IN4: Hold regeneration

Examples of use: stop the regeneration where it is until the contact goes back (example: wash the softener  until the drain’s conductivity goes into expected range back, wash the filter until the turbidity goes into the expected value back).
