Inherent Entrapment Sensor – (IES)
• Normally closed pressure switch on pump manifold
• Senses uid ow “above” pressure relief valve indicating high pressure and possible gate obstruction
• An open contact during gate movement signals the Smart Touch Controller to put operator into “SAFE”
mode
• Ignored for the rst second of operation to get past starting pressure spike
• An open contact while the gate is not operating will generate Err2 – disconnected IES
• A second open contact, in either direction of travel, will lock the machine out and the “ENTR”, or
entrapment mode, appears on the display

In the 50VF series SlideDriver™, a communication protocol allows the Smart Touch
Controller to constantly monitor the Variable Frequency Drive (VFD) and record
events in the STC history log. The history log is easily accessible using the HySecurity
S.T.A.R.T. program and a PC laptop computer.
With the ModBus RTU:
• Reduction in eld calls is likely because the STC resets VFD faults or error
codes upon receiving a new command.
• Quality issues with the site power are controlled better which results in less
intermittent operator problems.
• Smoother operator acceleration and deceleration enhances gate travel.
All 50VF2-3 series SlideDrivers shipped after January 1, 2012 have the new ModBus
cable and RTU communication protocol installed. If you need replacement parts for
your existing 50VF series operators, be sure to have the serial number of the
operator available when you order parts.
If you install a new 50VF2/3 operator, the speed is factory set at 2 foot per second (2 ft/s).
To change the speed, you will need to access the Installer Menu.
• SP 2 sets the 50VF2/3 speed to approximately 2 ft/s.
• SP 3 sets the 50VF2/3 speed to approximately 3 ft/s.
Refer to “Emergency Fast Operate (EFO) in
SlideDriver 50VF-series” on page 28.
• SP 0 and SP 1 are not used. (If you change the setting to 0 or 1, the operator will
not run.)
