Product catalog summary
Overview: The EX Tank Compartment Alert is a battery-powered device designed for monitoring fluid levels in remote tanks, providing audible and visible alarms for high-level or bund alerts. It is suitable for industrial applications in hazardous atmospheres up to Zone 1, including gas, vapors, and mists.
Intrinsically Safe Rating: Ex ia IIB T4. Certification details can be obtained via [email protected].
Installation: The device should not be installed in Zone 0 due to electrostatic risks. It supports multiple level switches, specifically monitoring float terminal indicators through probe connections J1 and J2 for high/bund and low/bund alerts, respectively.
Testing: Before installation, test the unit by connecting the probe and verifying the alarm operation. Ensure correct probe connection using a multi-test meter if necessary.
Fitting to the Tank: Requires a 1.5” M BSP fitting for CTS 5m standard probes. Adjust the probe drop by pulling the cable through the electric gland and secure it. Use the blue label to indicate unused alarm functions.
Operation:
  • Continuous Level Switch: Activates a continuous siren and flashing indicator for 120 seconds, followed by short siren bursts every 20 seconds until a 60-minute timeout, probe deactivation, or manual cancellation.
  • Test Alarm Key: Simulates full function test of the probe activation and release.
Maintenance: Periodic testing of the alarm and battery condition is required. Replace batteries in a non-hazardous area, ensuring correct polarity and secure mounting with a cable tie.
Specifications: The device has specific intrinsically safe parameters, including U0 = 6.6 V, I0 = 124 mA, P0 = 170 mW, C0 = 400 µF, L0 = 0 mH, Ci = 25µF, and Li = 4.4µH. Respect safety parameters when using third-party float switches.
Dimensions: Mounting holes are diagonally 180mm apart, with overall dimensions of 110mm x 58mm x 90mm.

CTS ATEX Approved Tank Alarm - Manual-1

INSTRUCTION SHEET The EX Tank Compartment Alert is battery powered and enables the monitoring of the fluid in the remote tank. It may be set to provide a high level / Bund alert audible and visible alarm. It is used in association with a magnetic level switch fitted to the tank. The intended use of the alarm is for industrial applications in hazardous atmospheres of up to Zone 1: gas, vapours and mists. Intrinsically Safe Rating - Ex ia IIB T4 Copy of the certification is available from [email protected] Installation (Typical) Note : Due to the potential electrostatic risk of the plastic membrane and the light metal enclosure the apparatus must NOT be located in a Zone 0 Multiple Level Switches The EX Tank Compartment Alert can monitor the following switches Switch 1 (Probe Connection) Switch 2 (Probe Connection) High / Bund Low / Bund

Testing After unpacking, the unit should be tested before installation. Connect the probe and test the operation of the float to correspond to the correct operation of the alarm. On some probes the float can be reversed to set the desired alarm or some probes have 3 cables so choosing the correct pair is important. If in doubt check operation with a multi test meter before connecting to the alarm. Fitting to the tank A 1.5” M BSP fitting is required if using CTS 5m standard probes. Adjust the probe drop into the tank by pulling the cable through the electric gland on top of the cap and then tightening...
