Operating instructions WAVE TTA

• Introduction

WAVE TTA is an accurate and stable signal

converter / isolator / alarm generator for use in

measurement and control systems.

• Conversion (current to voltage, and vice

versa)

• Isolation of temperature sensor and DC

inputs

• Linearization of temperature sensor inputs

• Transmission of sensor signals over long distance

• Characterising signals from DC transmitters

• Process alarm generation

• Relay control between high and low values

DANGER!

This product may be connected to potentially lethal

voltages!

CAUTION!

• Before you remove or mount the unit, turn-off the

power supplies – i.e. to the instrument and to the

relays, if used.

• Don’t remove the electronic boards out of the

housing.

• Follow ESD installation regulations, including the EMI

precautions given

• cULus – Approval for WAVE TTA EX

Class 1, Division 2 / Zone 2 markings (for WAVE TTA EX)

DANGER!

A. This equipment is suitable for use in Class I, Division

2, Groups A, B, C and D hazardous locations or

nonhazardous locations only or the equivalent.

B. EXPLOSION HAZARD – Substitution of components

may impair suitability for use in Class I, Division 2

environments.

C. EXPLOSION HAZARD – The area must be known to

be nonhazardous before servicing/replacing the unit

and before installing or removing I/O wiring.

D. EXPLOSION HAZARD – Do not disconnect

equipment unless po

wer has been disconnected and

the area is known to be non hazardous.

DANGER!

• Do not disconnect while circuit is live unless area is

known to be non hazardous.

• Devices type WAS6 TTA EX and type WAZ6 TTA EX

shall be installed in an enclosure in type of protection

Ex n or Ex e, providing a degree of protection of at

least IP54. Cable entry devices and blanking elements

shall fulﬁl the same requirements.

• A transient protection device, set at a level not

exceeding 40% of the rated voltage, shall be provided

to prevent the supply voltage (Terminals 24...26) from

being exceeded.

• A transient protection device, set at a level not

exceeding 40% of the rated voltage, shall be provided

to prevent the rated voltage of the digital relay outputs

(terminals 34...36 and 44...46) from being exceeded, if

they switch a power supply signal of other apparatus.

•Indicators

Status LED green

• Status ‘Alarm’ – on

• Status ‘ON delay is active’ – ﬂashes at 0.1 s on, 1.5 s off

• Status ‘OFF delay is active’ – ﬂashes at 1.5 s on, 0.1 s off

Conﬁguration

DANGER!

The conﬁguration socket must only be used for

conﬁgurating in non-hazardous areas!

The WAVE TTA will be conﬁgured with the software TTA-Set and the

interface module CBX100 USB or CBX200 USB. The software

TTA-Set and the user manual are available to download for free on

the Weidmüller website www.weidmueller.com.
