Setting And Adjustment; Selecting The Power Supply Of The Fans - Trane MERCURY EDAB 1105A Technical Manual

SETTING AND ADJUSTMENT

Selecting the power supply of the fans

WARNING! Before establishing the electrical
connection, make sure that the power supply
is off. Also ensure that it is not possible to
reconnect the power during the operation.
WARNING! In the case of a unit with ducts, the
load loss from the exhaust duct must be less
than 100 Pa.
In the following table the voltage levels for each model
working in the standard version are given.

HOW TO ADJUST FAN SPEED
In the E*CB three phase models the rotation speed of the
fans be varied by using the ATR transformer (F1).

To obtain the required prevalence of the implant, it is possible
to vary the voltage by selecting one of the following levels,
suitable for models from 0070:
140V -160V -180V -190V -200V -210V -220V -230V
models from 0100 to 0270:
230V - 250V - 260V - 270V - 280V - 290V - 300V - 310V -
320V - 340V - 360V - 380V - 400V.
models 0340 - 0400:
150V - 180V - 200V - 230V - 240V - 260V - 280V - 300V -
320V - 340V - 360V - 380V - 400V.
In the following table the maximum pressure available
(expressed in Pa) for each voltage level of the transformer
is indicated. The values are given for the maximum air flow
(expressed in m3/h).
