UMD-SRB01
Version 4
Indication of the system status will be provided by LEDs i.e. power on, monitoring,
brakes set OK and emergency stop.
In addition to this there is a small visual display showing a text interface
explaining the status and warnings.
The UMD-SRB01 has two switches, one is an emergency stop button which when
pressed will immediately deploy the brakes. The other switch requires a key to
operate it, this is because regulations require a competent person to reset the
brakes in the event of them being deployed. So to prevent any unauthorised
tampering or resetting or bypassing of the system a key is used. We supply 2
keys per system; these should only be made available to competent persons. The
key switch will allow the brakes to be reset and the system to bypass the motion
detection, during maintenance, etc.
An audible alarm is included within the UMD-SRB01 controller; this will beep
at different rates, one slow pulse for bypass mode and a quicker pulse for
reset mode.
Signals
Controller input power supply will be 230V or 110V AC 50/60Hz, it has an internal
12v DC control voltage, power supply and battery backup.
The system requires the following signals and connection to the external
contacts to enable it to operate.
1. A car Door Open / Closed Input signal.
2. A landing Door Open / Closed Input signal.
These inputs should be a connected to a Dry / volt free, normally open, pair of
relay contacts wired parrallel. It only requires a maximum switching current of
0.25A 12V DC.
3. An over speed OK signal, normally closed when no over speed,
opens when lift is over speeding.
Please note if the lift loses mains power the above door signals will open,
therefore the third signal we need must be connected directly to the over speed
governor switch, as if this signal opens the brakes will be immediately deployed.
Output signals from the controller will be volt free relay contacts. The contacts
are rated for up to 6Amp Max at 250VAC. These are:-
4. Main Lift Safety Circuit Output Signal.
5. Main Lift Alert Output Signal
