What to do if the Power LED is not lit on my Eaton Industrial Electrical?
If the Power LED is not lit on your Eaton Industrial Electrical, you should first check the polarity and integrity of the trunk cable connections to the enclosure. Also, verify that the d.c. supply powering the incoming trunk is operating correctly.
What to do if the power LED is not lit on my Eaton Control Unit?
If the power LED on your Eaton Control Unit isn't lit, verify the polarity and integrity of the trunk cable connections to the enclosure. Also, check that the d.c. supply powering the incoming trunk is operating correctly.
What to do if alarms on my Eaton Security System remain on and cannot be reset?
If alarms are set to operate from normally closed contacts and the signal supply fuse blows, all alarms will operate as though an alarm has occurred. To resolve this, check the signal supply fuse F1 (rated at 125mA), located in the top right-hand corner of the unit when viewed from the rear, to see if it has blown. Also, ensure that the inputs have been correctly set to operate from either a normally open (N.O.) or normally closed (N.C.) configuration and haven't been accidentally inverted.
How to fix the audible alarms not sounding on my Eaton Security System?
Each channel can be selected to operate either of the two integral horns / horn relays as required. Internal horns and horn relays are enabled by placing the following switches to the ON position on the SPR Card: HNA – SW5 - Position 5, HNB – SW5 - Position 6. Each pair of channels can be set to activate either of the audibles using the following switches located on each alarm module: Channel 1 & 2 HNA – SW4 Position 7 set to ON, HNB – SW4 Position 8 set to ON; Channel 3 & 4 HNA – SW6 Position 7 set to ON, HNB – SW6 Position 8 set to ON.
What to do if signal inputs that alarm and quickly return to normal are not being picked up by the Eaton Security System annunciator?
Check that the response time has been set to suit the application.
Why individual repeat relays do not act as slaves of the signal input on my Eaton Security System?
The operation of the repeat relays is selectable by the user to either follow the signal contact or to remain in the alarm state until the input has returned to normal and the operator has cleared the alarm.
How to troubleshoot a non-lit green LED for supply 1 and active power failure alarm on my Eaton Security System?
Measure the voltage on the power input terminals marked supply 1 located on the rear of the unit and verify that the level matches the requirement and is connected in the polarity indicated.
How to troubleshoot a non-lit green LED for supply 2 and active power failure alarm on my Eaton Security System?
Measure the voltage on the power input terminals marked supply 2 located on the rear of the unit and verify that the level matches the requirement and is connected in the polarity indicated.
What to do if no alarm occurs on the annunciator when the signal input contact closes or opens on my Eaton Security System?
Check that the signal supply fuse F1 rated @ 125mA, located in the top right hand corner when viewed from the rear of the unit, is in working order and check that the corresponding signal supply voltage is present on the customer terminals on the rear of the unit which can be measured between terminals OVC and any of the terminals marked C (Common) located at the top of each row of signal input terminals.
How to solve the Individual channel Repeat Relay contact is Normally Closed in the non alarm state but should be Normally Open on my Eaton Security System?
Each pair of repeat relays can be set to normally energised or normally de-energised using switches located on the Alarm Card and the contact state can also be selected as normally open or closed.
The MTL 9492-PS-PLUS is an intrinsically safe power supply module designed for use in hazardous areas, specifically for powering MTL 9460-ET series Ethernet modules. It is a key component in providing safe and reliable power within industrial environments where explosive atmospheres may be present.
The primary function of the MTL 9492-PS-PLUS is to convert a 24V DC safe area/Zone 2 supply into an intrinsically safe 12V DC nominal output. This intrinsically safe output is crucial for powering Ethernet modules located in Zone 1 hazardous areas, ensuring that no ignition source is created by the electrical supply. The module offers two distinct intrinsically safe outputs: an Ex ia IIB output and an Ex ib IIB output. The Ex ib IIB output provides a higher usable output power, which can be advantageous depending on the specific application and the gas group/zone requirements.
The module incorporates several features to enhance reliability and safety. It includes LED power indicators for both input and output, allowing for quick visual confirmation of operational status. Internal current limiting and electronic auto-reset circuit breaker action protect the module from short circuits or overloads. This protection mechanism minimizes power dissipation during fault conditions, contributing to improved system reliability.
