4.5.4 POWER SUPPLY WIRING
When not directly supplied from mains (type PM), the external power supply must be an
approved ELV source, insulated from AC mains by double / reinforced insulation per CSA
C22.2 No. 61010-1 / UL61010-1 / EN/IEC 61010-1.
The F093-P can be powered from an external power supply. An internal power supply is also
available in the form of a lithium battery. When both external and internal power supplies are
available, the internal power supply is interrupted and will act as a backup supply. Note that the
optional backlight only works with an external power supply.
4.5.5 TACHOMETER SUPPLY
For type PB / PX
– Terminal 3: limited tachometer supply
With these types of power supply, there is no real supply output available but only a limited power
supply. This power supply SHOULD NOT be used to supply the tachometer electronics, converters
etc. as it will not provide adequate sustained power! All energy used by the tachometers pick-up will
directly influence the battery life-time. It is strongly advised to use a "zero power" pickup such as a
coil or reed-switch when operating without external power. It is possible to use some low power NPN
or PNP output signals, but the battery life time will be significantly reduced (consult your distributor).
The supply at terminal 3 is fixed to 1.2V DC for coil type inputs and 3.2V DC for all other types of
inputs (set by firmware).
For type PD - Terminal 6: tachometer supply 8.2V
Besides offering the limited sensor supply on terminal 3 (see above), type PD also offers a real
supply of 8.2V DC, for example to power a Namur sensor, on terminal 6.
For type PF / PM
– Terminal 7: tachometer supply, 8.2V, 12V or 24V
Besides offering an identical limited supply on terminal 3 as described above, type PF and PM offers
a real power supply. The tachometer can be externally powered with 8.2V, 12V or 24V DC (max.
400mA@24V). The voltage is selected with the three switches inside the F093-P.
•
Be sure that all the leads to the terminals are disconnected from the F093-P when the
internal plastic protection cover has been removed !
•
HIGH VOLTAGE 400V !! NEVER connect the mains power supply to the F093-P when
the plastic protection cover has been removed !!!
To gain access to the switches, first remove the terminal strip(s) after which the internal plastic cover
can be removed. The switches are located on the right hand side as indicated:
