WARNING
Do not connect/disconnect equipment unless power has been switched off or the area is known to be non-hazardous.
Ne débranchez pas l’equipement tant que l’alimentation est coupée ou que la zone est connue pour être non dangereux.

IMPORTANT:

• Use appropriately classified and listed Power Supply (Limited Power Source, or LPS). Follow all applicable wiring codes and regulations.
• Peripheral equipment must be suitable for the location in which it is used.
• There are no non-incendive circuits or non-incendive field wiring within or associated with the unit.
• Only technically qualified service personnel are permitted to install or service the equipment.
• Do not disassemble the system – no user-serviceable parts inside.
• Do not operate the equipment if it has been damaged.

PROVIDE SUITABLE PANEL ENCLOSURE, AND DETERMINE LOCATIONS FOR TOUCH 1500-EX ASSEMBLY IN PANEL

1. Provide suitable panel enclosure To protect its electronic components, the Chemelex Touch 1500-EX must be mounted in a panel with a minimum IP32 (Type 1) enclosure for non-hazardous indoor locations. An IP52 (Type 12) or better enclosure is recommended. An IP54 (Type 4) or better enclosure is required for hazardous locations. The Touch 1500-EX assembly comes with a sealing gasket and hardware to mount the enclosure.
   Note: The Touch 1500-EX is designed for operation in ambient temperatures from –40°F to 140°F (–40°C to 60°C). If the ambient temperature is outside this range, a space heater and/or cooling fan will be required in the panel.
   
2. Determine locations for the Touch 1500-EX assembly in the electrical panel
   The Touch 1500-EX should be located on the front of the panel  near eye level (for convenient viewing). The Touch 1500-EX assembly is an electronic unit and must not be located where it will be exposed to strong magnetic fields or excessive vibration. Conditions of Safe Use in Hazardous (Explosive) Atmospheres The equipment must be installed in a low risk mechanical danger environment. The equipment shall only be used in an area of at least pollution degree 2, as defined in IEC/EN 60664-1.
   The equipment shall be installed in a back enclosure with tool removable door or cover that provides a degree of protection not less than IP54 in accordance with IEC/EN 60079-0 rated for.
   • Internal and external ambient of: –40°F to 140°F (–40°C to 60°C)
   • ATEX / IECEx: Zone 2 or better
   • US / CAN: Class I Div 2 or better
   • Provisions shall be made external to the equipment to provide transient protection at a level not exceeding 140% at the power supply terminals

CUT OPENING AND MOUNT TOUCH 1500-EX ON FRONT OF PANEL

1. Locate the Touch 1500-EX on front of panel
   Locate the Touch 1500-EX assembly on the front of the panel at a level convenient for viewing. Make sure the cover on the back of the assembly will not interfere with existing panel hardware.
   
   Note: Cutting the opening for the display is a craft sensitive procedure; if it is not done correctly, the panel door can be damaged. The procedure for laying out and cutting the opening for the display must be undertaken with care, and by personnel qualified and experienced in panel construction.
2. Prepare and mark the position of the display opening and mounting holes
   • Use the cut-out directions to lay out the opening for the Touch 1500-EX display.
   • Apply two layers of masking tape around the outer perimeter of the intended opening to prevent scratching the panel surface with the jigsaw.
3. Cut the display opening
   Cut the opening for the Touch 1500-EX with a jigsaw using a 24 TPI blade. Take care not to damage the panel door. Remove all rough edges and burrs with a metal file before proceeding.
4. Drill the mounting holes
   Drill the 16 holes with a 3/16″ (5 mm) drill bit to mount the Touch 1500-EX assembly in the panel.
   Note: The following steps are most easily accomplished if the panel door is on a horizontal surface.
5. Mount the user interface assembly onto the panel door
   • Place the Touch 1500-EX assembly in position; the sixteen studs go through the sixteen holes on the Touch 1500-EX assembly mounting plate (see figure below).
     
   • Place the supplied 6/32 in Kep nuts on each of the sixteen mounting studs. Fasten only hand tight.
     
   • Look at the front of the panel, and align the Touch 1500-EX assembly so it is level (loosen nuts if necessary to reposition the Touch 1500-EX assembly).
   • After the display is properly positioned, tighten the nuts to 0.62 Nm (5.5 in/lb) of torque using a 5/16″ (8 mm) in-line torque wrench. Do not overtighten and risk damage to hardware.
   • Tighten Kep nuts in the sequence shown for proper sealing.

TOUCH 1500-EX CONNECTION DIAGRAM

CONNECT POWER

Connect 24 Vdc to the male power connection fitting located on  the left side of the Touch 1500-EX. Make sure to connect the grounding terminal. Ensure the cables are routed through  the cable clamp as shown.
Note: The Touch 1500-EX is rated for 12 -27 Vdc. Since the  NGC-40 modules are rated for 24 Vdc, we have used  this voltage to also power the Touch 1500-EX. As a result, the recommend alarm relays and lights detailed in the “Additional Materials” are rated for 24 Vdc.
Provision shall be made external to the equipment to provide transient protection at a level not exceeding 140% at the power supply terminals.

INSTALL COMMON ALARM LIGHT AND ALARM RELAYS

Mount the alarm relay on a DIN rail inside the panel enclosure. Mount the Alarm light on the panel’s door below the touch screen.
Per the below drawing, bring 24 Vdc to the Relay Driver Output at the bottom of the touch screen, to the alarm relay and alarm light.
Per the below drawing, wire between the Relay Driver Output, alarm relay, and alarm light.

COMMUNICATION

The Touch 1500-EX has two isolated RS-485 ports located at the bottom.

• Field Side Port (DATA 1 +/-)
  The RS-485 port labeled “DATA1+ and DATA1-” is the field side port that is used to communicate with ModBus devices (ie. NGC-40 Bridge Module, Elexant 4010i, Elexant 4020i, Elexant 3500i, RMM2 and RMM3).
• Remote Port (DATA 2 +/-) – Optional
  The RS-485 port labeled “DATA2+ and DATA2-” is the Host side port that is used to communicate with to a host computer or to a DCS.
• Local Host Port (RS-232) – Optional
  The RS-232 port labeled “RS-232 1” is the RS-232  port that can be used as local Host port that is used  to communicate with to a host computer. If the RS-232 port is utilized, the supplied female to female, 9-pin null modem adaptor cable must be used.
• Ethernet Port – Optional
  The Ethernet Port labeled “Ethernet Port 3” is the Host side port that can be used to communicate to a host computer (using Raychem Supervisory Software) or to a DCS. Ethernet Ports 1 & 2 are inactive and cannot be used.

RS-485 CONFIGURATION SWITCHES

The configuration switches are found on the bottom side of the Touch 1500-EX. Refer to the table below for settings.

	Position
Switch	On	Off	Comments
Pull-down (PD)	(As-shipped default) RS-485 network “–” signal is forced to a determinate state when idle.	RS-485 network “–” signal is not forced to a determinate state when idle.	One device (typically this Touch 1500-EX) on the RS-485 network should force the network “-“ signal to a determinate state.
Pull-up (PU)	(As-shipped default) RS-485 network “+” signal is forced to a determinate state when idle.	RS-485 network “+” signal is not forced to a determinate state when idle.	One device (typically this Touch 1500-EX) on the RS-485 network should force the network “+“ signal to a determinate state.
Termination (TERM)	(As-shipped default) RS-485 network is terminated with 120-ohm resistor.	RS-485 network is not terminated.	Terminate the device (Touch 1500-EX or other) that is at each end of the RS-485 network, for a total of two terminated devices. No other devices on the network should be terminated.

RESET SWITCH
The Reset switch can be found on the bottom of the Touch 1500-EX. A pointed object is required to press the reset switch and restart the Touch 1500 software.

SERVICING
The Touch 1500-EX contains no user-serviceable parts. Contact your Chemelex representative for service and a return authorization number if required.

CLEANING
The touch screen area of the Touch 1500-EX may be cleaned with a damp cloth. Typical window cleaning agents may be applied to aid in the removal of dirt, dust and grease. Do not use abrasive cleaners.
