The error is stored permanently. Only by pressing the reset button on the control board the error of the
UCM safety circuit will be cleared and the lift should get back in normal operation, as far as the UCM-
brake actuator does not require additional measures. (for example, release of safety gear, etc.)
Maintenance:
There are no direct services or maintenance measures necessary. The safety control must always be
kept clean and dry. It must be ensured that the safety control is replaced after an operating period of
10 years or 3.5 million drives because the specified product life cycle of the safety relay has been
reached or exceeded.
Disposal and Recycling:
Unusable or irreparable devices and devices which have exceeded their lifecycle have to be disposed
in accordance to the applicable waste disposal regulations for electronic waste. The plastic housing
can be disposed as residual waste.
Included in delivery:
The scope of delivery includes the safety control ENA3, the manual and two special magnetic switches
(Encoder Typ C1511FDA0300S) for monitoring of the door zone.
The ENA3 safety control will be delivered in a plastic housing which can be fixed on a DIN rail and
should be installed in the control box of the lift.
The safety control system needs a power supply of 24 VDC (+ / - 10%).
On request, the necessary magnetic tape (20cm per stop), a power supply for a supply voltage of
115V to 230V can be delivered as well.
In addition the unit can be installed and delivered in an industrial plastic housing (IP65).
Ordering information and spare parts:
Consists of an ENA3 control device and ENA3-
NSE emergency power supply and extra
functions to supply power to an UCM brake
actuator which needs to be supplied during
power failure (f.e. speed governer).
