Overview

MOD-PD2LH

Helios Meter Shown with MOD-PD2LHRB1 Red Light / Horn and Reset Button. Meter Sold Separately.

The Helios can be provided with an optional light(s) with built-in 85 dB horn that comes mounted and wired to the instrument or as separate items to be mounted as the user desires. Meter is sold separately. The MOD-PD2LH Series is available in three different light configurations. The first option is a factory ordered Light / Horn with a color of either red, green, yellow, blue, or white. The second option is a Light / Horn the user determines the light color (red, green, yellow, blue or white) by connecting the appropriate wire. The third option is a Light / Horn with red, yellow, and green layers the user can turn on independently.

The MOD-PD2LH can be powered from the Helios’s 200 mA transmitter power supply with enough power left over to drive most transmitters.

The light(s) and horn can be controlled independently of each other via separate relays on the Helios. These relays can be programmed for automatic or manual reset action to satisfy a wide variety of audible and visual alarm applications. The light can be programmed to flash (not available on MOD-PD2LH5CB1) or stay steady-on.

The Light / Horn and Reset Button do not affect the Helios’s NEMA 4X rating, but do void its UL approval.

Note: The Light / Horn accessory is powered from the 200 mA transmitter power supply, so when this is installed, the meter’s transmitter power is downgraded from 200 mA. See Transmitter Power Supply specification for details.

Applications

There are a wide variety of ways these Light / Horn devices can be controlled by the Helios's four relays to satisfy visual and audible alarm applications. Please feel free to contact tech support to discuss your particular application. The following examples illustrate some typical applications.

MOD-PD2LH Models

MOD-PD2LH Wiring

Note: Unless otherwise specified, this MOD is shipped wired in the above fashion.

The MOD-PD2LH models are the simplest devices in the Series and are made up of a single-color light and horn. A typical way to use the MOD-PD2LH is to program the Helios so the horn can be silenced at any time via the Reset Button or F3 front panel button on the Helios, and light to reset automatically when the alarm clears:

RelayConnected toDefault Reset

4User DeviceAs user desires
1 Light can be wired to flash or stay steady on.

MOD-PD2LH5CB1

MOD-PD2LH5CB1 Wiring

Note: Unless otherwise specified, this MOD is shipped wired in the above fashion.

The MOD-PD2LH5CB1 shows one color at a time and the light color (red, green, yellow, blue or white) is determined by which wires are connected to power through the Helios's relays. A typical application for the MOD-PD2LH5CB1 might involve lighting up the red light to indicate low and high alarms using the Helios's four internal relays:

RelayPurposeRangeLight/HornAction
1Low alarm< 199Red lightAuto
3Low alarm< 199HornLatch
2All OK200 to 500Green lightAuto
2High alarm> 500Red lightAuto
4High alarm> 500HornLatch

MOD-PD2LH3LCB1-RYG

MOD-PD2LH3LCB1-RYG Wiring

Note: Unless otherwise specified, this MOD is shipped wired in the above fashion.

The MOD-PD2LH3LCB1-RYG can light up red, yellow or green bands as determined by which wires are connected to power through the Helio's relays. A typical application for the MOD-PD2LH3LCB1-RYG (and the default factory setting) might involve lighting up the green light to indicate everything is OK, the yellow light to indicate a High warning, and the red light to indicate a High alarm. The Horn will also sound at both the Warning and High alarms and can be manually reset at any time with the front panel reset button:

RelayPurposeRangeLight/HornAction
1All OK< 199Green lightAuto
2Warning200 to 500Yellow lightAuto
3Warning200 to 500HornLatch
2High alarm> 500Red lightAuto
4High alarm> 500HornLatch

Connections

MOD-PD2LH Connections

MOD-PD2LH Models

Connections shown for a red light model. For other MOD-PD2LH models, the red wire is the color of the light. Connect the red and black wires for a Steady On light and red and gray wires for Flashing light.

MOD-PD2LH5CB1 Connections

MOD-PD2LH5CB1

Connect the LED color to the plus supply and the black wire to the minus supply to turn the LED on. Be aware of limitations for applications requiring different color lights for different alarm conditions.

MOD-PD2LH3LC-RYG Connections

MOD-PD2LH3LCB1-RYG

Connect the LED color to the plus supply for a Steady On light and LED color and gray wires to the plus supply for Flashing light. The black wire should be connected to the minus supply.

Wiring Connections for MOD-PD2LH Models

Wiring Connections for Transmitter Powered by Helios

The Helios can be wired to power both the Light / Horn accessory as well as the transmitter input and isolated 4-20 mA output as the following diagram illustrates.

Internal Power Supply Connections

Wiring Connections for Transmitter Powered by External Source

Transmitters and sensors that require more than 163 mA must be powered by an external power source, such as the PDA1024 as the following diagram illustrates.

Power Requirement: No additional power required when installed in Helios. When mounted remote: 24 VDC
Transmitter Power Supply: The Helios's internal transmitter power supply is downgraded from 200 mA when it powers the Light / Horn. To determine the total downgrade, add the currents for the light(s) being used and the horn if used. If more power is needed, then consider the PDA1024-01.
MOD-PD2LH and MOD-PD2LH5CB1 Models:
Example: 17 mA (Red Light) + 20 mA (Horn) = 37 mA total current downgrade from the 200 mA supply. Left over current = 163 mA

ColorDowngraded by
Red17 mA
Green15 mA
Yellow23 mA
Blue15 mA
White42 mA
Horn20 mA

MOD-PD2LH3LCB1-RYG:
Downgraded by each color that is turned on and the horn.
Example: 33 mA (Yellow Light) + 38 mA (Horn) = 71 mA total current downgrade from the 200 mA supply. Left over current = 139 mA
ColorDowngraded by
