HAWK GLADIATOR SERIES
IECEx Zone 20
IECEx
(i20)
Equipment types:
AS2100 series Smart Admittance Switch
AS2200 series Remote Admittance Switch
CS3100 series Smart Conductivity Switch
CS3200 series Remote Conductivity Switch
1. General
This document provides instructions for the installation of Hawk Gladiator Admittance and
Conductivity Probe level sensing equipment for Zone 20 hazardous dust open vessel locations,
according to IECEx Certificate of Conformity IECEx ITS 08.0031X. IECEx certified equipment is
relevant in most countries of the world. This equipment can also be installed in Zones 21 and 22.
Hawk Gladiator series probes are industrial process level switches which detect the level of process
material on contact. The Gladiator series achieves this through three different designs - Admittance,
Conductivity and Vibration sensor probes.
The probe enclosure which would be located on the outside of a process vessel is Zone 21 and is
protected by the enclosure (Ex tD). The probe sensor is located inside the vessel is Zone 20 and is
protected by intrinsic safety (Ex iaD).
Gladiator Probes are available in both a Smart (integral) version and a Remote version connected to
a Gladiator System Amplifier located away from the Zone 20/21 area. Alternative marking labels
allow installation of Gladiator Admittance and Conductivity probes on both open and closed vessels.
2. Equipment Identification
The IECEx Zone 20 marking label is shown above.
If Hawk Sultan Acoustic Wave equipment is installed and mounted in Zone 20, 21 or 22 hazardous
dust areas, these User Manual Safety and Operating Instructions, the general Ex installation
regulations and the general installation regulations for electrical equipment must all be observed. The
installation of Ex instruments should only be made by trained personnel.

3. Putting Into Service
To put a Hawk Gladiator Unit safely into service, the following steps must be taken:
a) To be compliant, the equipment must be installed with Intrinsic Barrier devices as described in
Section 10, Intrinsic Safe Installation. Cables from both hazardous and safe areas must be
segregated from each other according to the appropriate Intrinsic Safe installation standards.
b) Follow the instructions in Typical Installations and Installation Guide, as well as the relevant
conditions on the IECEx Certificate of Conformity:-
Only to be powered by a suitably certified I.S. Barrier up to and including the values of 28V,
93mA and 651mW.
Parts of the probe are plastic, which may present an electrostatic hazard and should not be
rubbed or cleaned with a dry cloth.
c) Gladiator probes have cable glands located at one side of the housing. The enclosure section
above the process fitting can be rotated to prevent moisture ingress via the cable entries. Ensure
the cable glands are securely tightened to adequately seal the cable. An unused cable entry must
be fitted with the blanking plug and rubber gasket provided.
d) Correct wiring. Follow the instructions in the Wiring sections. Wiring should be in accordance
with relevant installation standards for hazardous area equipment or other local codes of practice.
e) Safe temperature. Temperature must not exceed the operating range of the Gladiator unit. In
particular, Ex rated equipment must not exceed the temperature limits shown on the marking
label.
f) Safe power supply. Power supply values must be according to the Specifications.
g) It is advised to provide a cover for the unit to prevent damage that could happen due to
environmental conditions.
h) Do not put into service where there is a possibility of contact with acetic acid.
4. Use
The instructions for safe use of the Gladiator Unit is as follows:
a) The Gladiator equipment must put into service safely. (see Putting Into Service, above).
b) This User Manual must be read and understood by any person involved with the unit.
c) Environment and installation conditions should be checked regularly.
d) When opening the cover of the any Gladiator unit, prevent dust, liquids or chemical substances
from getting inside the unit. Do not leave any cover open in rain or snow conditions.
e) The Remote Gladiator Probe requires a cable connection to a GSA series Gladiator System
Amplifier. The LCD display is visible through the clear lid of the GSA enclosure.
f) Before making any wiring or hardware configuration changes, it is important to disconnect
power from the equipment.

5. Assembling and dismantling
When installing the Gladiator Probe into a threaded nozzle, turn the hexagonal fitting with a suitable
open ended or adjustable spanner. Do not attempt to tighten or remove the unit by gripping the
upper part of the enclosure or lid, because it has almost a full turn of rotational freedom to align the
cable entries.
Moisture and dust must not enter the enclosure. Ensure the lid remains tightly sealed.
Cable entry points must be properly sealed.
6. Installation and Wiring
Carefully follow Typical Installations, Installation Guide and Wiring Diagram sections. Follow
all points listed in Putting Into Service, above. Wiring should be in accordance with relevant
installation standards for hazardous area equipment or other local codes of practice.
7. Adjustment
a) Gladiator Smart Probe models:
User controls and terminal connections can be accessed by unscrewing the lid. A strap wrench tool
can simplify removal of the lid.
See Smart Probe Setup Procedure in the user manual. Make adjustments with the aid of the user
manual if required. Then replace the lid by screwing down tight.
b) Gladiator Remote Probe models:
The Gladiator Remote Probe has a status indicator LED and no user adjustments. The screw lid can
be used to access the wiring terminals. A strap wrench tool can simplify removal of the lid.
To access the user controls on the Gladiator System Amplifier, unlock the clear cover using the lever
on the right hand side of the clear lid. Press this lever in the direction of the arrow (towards the lid)
to release the catch. The lid can then be swung open to gain access to the user control push buttons.
See Remote Probe Setup Procedure in the user manual. Close the lid when finished. To lock the
lid, press on the lower part of the lever, which moves the arrow symbol (in reverse) slightly away
from the lid, locking the lid closed.
c) Software Adjustment:
For software adjustment of Gladiator unit parameter adjustment and data entry, refer to instructions
in Entering Data, and all of the Setup sections. If GosHawk II software is to be used for parameter
adjustment and data entering from a lap-top computer, read and fully understand the information in
the GosHawk II Manual either supplied with the equipment or downloaded free from the Hawk website:

8. Application Conditions
a) Voltage Supply:
Must be according to the voltage supplies given in Specifications.
b) Temperature:
Must not exceed the operating temperature range stated in Putting Into Service, above.
c) Cable Connection:
Cables must only be replaced by the same cable type. If extending the cable, it must be
protected in a junction box and terminated in an enclosure suitable for the environment. Refer
to Wiring sections.
d) Earthing:
Hawk Gladiator equipment must be earthed to ensure that shielded cabling is effective.
e) Electrostatic Discharge:
See Putting Into Service (b) above. Do not rub or clean plastic parts with a dry cloth.
f) Industrial Conditions:
This equipment is designed for use in normal industrial conditions relating to humidity,
vibration, etc. If the user intends to operate the equipment in more severe environmental
conditions, the manufacturer or local distributor should be consulted for advice.
