The Innotech GenII CSAH REM Momentary Digital Input Control Station Module is an expansion device for the Genesis range of Digital Controllers.

The module is powered by 24VAC and provides a limited User Interface to the Genesis Controller. There are no physical connections between field equipment and the GenII CSAH REM, all input/output values are edited and viewed on the wall unit.

The GenII CSAH REM may be located remotely from the Genesis Controller providing a distributed User Interface for the system.

The GenII CSAH REM is configured via the wallplate and programmed via the Gen2Config Software.

The GenII CSAH REM communicates with the Genesis Controller via the REM Comms port. The remote link uses RS-485 at a baud rate of 38400. For pre-Version 5 controllers, a Gen II RMI Remote Module Interface is required. Please refer to DS15.01 for further information.

Expands Genesis Controller capabilities by providing a numeric output display, numerical value input, a single momentary digital input switch and single LED display output for distributed control via RS485. The GenII CSAH REM Module provides a visual display of a control value and a means to set a parameter.

Application Notes
A Genesis Controller must have version 4.0 firmware installed to support REM Modules. Version 4.1 or higher Config Software must be used to configure a Genesis Controller that has a CSAH REM Module connected to it.

One Genesis Controller can have up to 9 GenII CSAH REM Modules* connected to it via the REM comms bus.

For detailed connection information to the pre version 5 Genesis Digital Controller Family, please refer to Innotech Cabling Manual (.pdf 1.54MB).

Power Supply

Voltage: 24 volts AC ±10% @ 50/60Hz.
Power Consumption: 3VA max.

The operating voltage must meet the requirements of Safety Extra Low Voltage (SELV) to EN60730. The transformer used must be a Class 2 safety transfomer that has the energy and voltage limiting characteritics as described in the National Electrical Code, ANSI/NFPA70. It must also be sized and fused in compliance with local safety regulations.

Inputs

Push buttons for adjusting control values.
Momentary Push button for input of “digital func tion”.

Outputs

No physical ouputs.
Display of Temperature and Setpoint.

Terminal Identification

1 = 24V AC Supply.
2 = 0V AC Supply.
3 = Earth.

NOTE - TERMINAL 3 is for the protection of the Comms circuitry and must be connected to a good electrical bonded Earth.

COMMS Connection

SHLD 1	=	Shield from incoming Comms Cable.
+	=	RS 485 (+) signal.
-	=	RS 485 (-) signal.
SHLD 2	=	Shield from outgoing Comms Cable.

Temperature Ratings

Storage 0 to 50°C non-condensing.
Operating 0 to 40°C non-condensing.

Enclosure
The GenII CSAH REM Modules are housed in switchplate that mounts in standard electrical wall plates.

Colour: White
Wall mounted.

Installation

The Cable run between the GenII CSAH REM and the GenII RMI should not exceed 500 mtrs. The Comms wiring requires cable especially suited for RS485. Other shielded cable is not suitable and will cause spasmodic Comms failures.
Strictly follow the guidelines when installing the Comms wiring as outlined in the Genesis II Installation Manual.
Mount the GenII CSAH REM in a dry and clean location free of excess vibration.

The REM address must be set by programming Parameter 0. Please refer to the Program Functions section of this data sheet for more specific information regarding this.

Wiring

The cable used for RS485 Comms must be shielded single twisted pair, 120 ohms character impedence, 36 to 45pF per metre capacitance between conductors.
The Comms cable must be organised as a bus topology. That is, starting at one end, devices are connected to it until the other end of the cable is reached. No “stubs” are allowed. To connect a device to the cable, as cut is made in the cable at the point where the device is to be situated along it. Then, the two new ends of the cable are wired into the device. The shields from the two new ends are then terminated into the terminals marked SHLD1 and SHLD2. Refer to the Genesis Network Installation Instructions for more information.
