Installation Guide for Raychem Touch 1500-EX User Interface Terminal

Quick Guide for Installation

The Raychem Touch 1500-EX is a panel-mounted display designed for industrial environments. Installation requires precise cutting of the panel door and secure mounting using the provided hardware. Ensure the environment meets IP54/Type 4 requirements for hazardous locations. All electrical connections, including power and communication, must be performed by qualified personnel.

Product Description

The Touch 1500-EX is a 15-inch color XGA display with a 5-wire resistive touch screen. It is rated IP65 (Type 4X) on the front panel and is suitable for both indoor and outdoor use in non-hazardous and Class I Div. 2 / Zone 2 hazardous locations.

Installation and Mounting

Panel Preparation:

• Locate the unit on the front of the panel at eye level.
• Use the provided cutout dimensions to mark the opening.
• Apply masking tape around the perimeter to prevent scratching the panel surface.
• Cut the opening using a jigsaw with a 24 TPI blade.
• Drill 16 mounting holes using a 3/16 inch (5 mm) drill bit.

Mounting Procedure:

• Place the assembly into the cutout.
• Secure the unit using the 16 supplied 6/32 in Kep nuts.
• Tighten the nuts in the specified sequence to ensure a proper seal.
• Use an in-line torque wrench to tighten nuts to 0.62 Nm (5.5 in/lb). Do not overtighten.

Electrical Connections

Power Supply:

• Connect 12-27 VDC to the power fitting on the left side of the unit.
• Ensure the grounding terminal is connected.
• Route cables through the cable clamp.

Alarm Outputs:

• The unit features transistor open collector outputs (5-30 Vdc, max sink current 500 mA) to drive external relays.
• Mount alarm relays on a DIN rail inside the panel.

Communication and Configuration

Ports:

• RS-232: Local host port (9-pin D sub male).
• RS-485: Two isolated ports (Field Side and Remote).
• Ethernet: 10/100 Base-T port (Port 3 active).

RS-485 Configuration Switches:

Located on the bottom of the unit, these switches control network behavior:

• Pull-down (PD): Forces "-" signal to a determinate state when idle.
• Pull-up (PU): Forces "+" signal to a determinate state when idle.
• Termination (TERM): Terminates the network with a 120-ohm resistor.

Maintenance and Troubleshooting

Cleaning:

• Clean the touch screen area with a damp cloth.
• Use typical window cleaning agents if necessary.
• Do not use abrasive cleaners.

Reset:

• A reset switch is located on the bottom of the unit. Use a pointed object to press it and restart the software.

Servicing:

• The unit contains no user-serviceable parts. Contact a Chemelex representative for service.
