ES SERIES HUMIDIFIERS SAFETY DEVICES AND POWER SUPPLY
ELECTRIC CONNECTIONS
Connect the electric power supply to the humidifier terminal box bringing 230V voltage to
clamps R and N for single-phase models, or 400V voltage + neutral to the RST and N
clamps for the three-phase models.
It is compulsory to connect the yellow/green clamp with initial PE to the earth system of the electric
mains. If required, check earth system efficiency.
Leave jump in clamps 60 and 61 of the terminal box or, if required, replace it with a normally
closed emergency contact.
Clamps 62 and 63 of the terminal box are arranged for fan unit power supply; in case of unit
installation, consult the use manual attached thereto.
ES AND OEM SERIES SENSORS AND CONTROL SIGNALS CONNECTIONS
The humidifier envisions eight different functioning mode settable from S9 software variable
described in chapter 3.5 and from specific electric connections.
Also necessary is the enabling to In1 digital input clamps 24 and 25 on the MasterHUM2
microprocessor board for all functioning mode (enabling = closed contact between clamps 24 and
25). Without enabling, the display alternates the OFF writing with normal displaying.
Below are the specific connections for every functioning mode.
If wanting to connect the humidifier with humidity probes not supplied by PEGO s.r.l.,
contact the after-sales assistance centre to verify hardware compatibility of the probe
with the humidifier.
- [S9=0] ON/OFF Functioning:
This type of functioning envisions steam output in 2 ways only: no output or maximum output.
The consent is usually given by a potential free contact coming from an electrical panel which,
in turn, is controlled by a humidostat. Set the second level variable S9=0 and connect the
consent to clamps 24 and 25 of the Master HUM2 board (Enabling present with closed contact).
