Overview

Transform a Precision Digital meters and controllers housed in an enclosure into an efficient display, control, and alarm system with the MOD-LH series. It provides a light/horn to boost visibility of alarm conditions, a button that connects to the meter's digital input to control or reset the alarms, and hole drilling on the enclosure for both the light/horn and button to make user installation and wiring quick and easy. Enclosure and meter are sold separately.

The MOD-LH series is compatible with a wide range of Precision Digital NEMA 4 and NEMA 4X enclosures as well as meters and controllers including the ProVu, Trident, Loop Leader, and ConsoliDator+ Series. Overall, the MOD-LH series is a simple solution for Precision Digital meters and controllers that adds audible and visual ways to indicate critical alarms.

Installation of the light/horn accessory voids all of the PD2 and PD4 agency approvals. The NEMA 4X and IP65 ratings are not affected.

MOD-LH Series Light Color Options

Light/Horn

The light/horn is available in three different light configurations and each comes with a built-in 85 dB horn.

The first light option is a single color light in either red, green, yellow, blue, or white. The second light option is a user selectable light with five color options in either red, green, yellow, blue or white. Simply connect the appropriate wire to display the desired light color. The third option is a light stack with red, yellow, and green lights that can turn on independently (not compatible with PD4).

The light can be wired to flash (not available on MOD-PD2LH5CB1) or stay steady on. Both the light and horn can be controlled independently of each other using separate relays on the meter, and may be reset in a variety of ways based on the connected meter's relay reset capabilities.

MOD-LH Series Button

Button

The button connects to the meter's digital input and it can be used to remotely control the light/horn such as resetting, acknowledging, or silencing an alarm. Nine (9) printed labels are provided to identify the button's action including: RESET, BATCH, ACK, TARE, SILENCE, STOP, START, PAUSE, and START/STOP.

MOD-LH Series Button Labels Provided (9) Printed Labels Provided

Control Capabilities

The light and horn can be controlled independently of each other using separate relays on the Precision Digital meter they are connected to. These relays can be programmed for automatic or manual reset action to satisfy a wide variety of audible and visual alarm applications.

Power Options

Precision Digital meters with an internal transmitter power supply can provide up to 200 mA to power the transmitter and other devices including the light/horn. See Specifications for details on power consumption.

If a meter connected to the light/horn does not have an internal transmitter power supply or more power is required than the meter provides, then consider the PDA1024-01 24 VDC transmitter power supply.

Hole Drilling Locations

All MOD-PD2LH models provide hole drilling on enclosure for light/horn and button. See below for hole locations for both the light/horn and button.

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.

Applications

There are a wide variety of ways these light/horn devices can be controlled by Precision Digital meter's relays to satisfy visual and audible alarm applications. Feel free to contact tech support to discuss your particular application. The following examples illustrate some typical applications.

MOD-PD2LH Models

MOD-PD2LH Wiring
PD2 meter with internal transmitter power supply connections shown

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 meter so that the horn can be silenced at any time via a button connected to the meter's digital input or via the F3 front panel button, and the light to reset automatically when the alarm clears:


RelayConnected toDefault Reset
1Flashing Light(1)Auto reset
2HornSilence with Button at any time
3User DeviceAs user desires
4User DeviceAs user desires
1 Light can be wired to flash or stay steady on.

MOD-PD2LH5CB1

MOD-PD2LH5CB1 Wiring
PD2 meter with internal transmitter power supply connections shown

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 meter’s relays. A typical application for the MOD-PD2LH5CB1 might involve lighting up the red light to indicate high and low alarms and the green light to indicate everything is OK using a Precision Digital meter's four internal relays:

MOD-PD2LH3LCB1-RYG

The MOD-PD2LH3LCB1-RYG can light up red, yellow or green lights as determined by which wires are connected to power through the meter'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 via a button connected to the meter's digital input or via the F3 front panel button:

Green29 mA
Yellow33 mA
Horn38 mA
Example:
33 mA (Yellow Light) + 38 mA (Horn) = 71 mA total current needed from the 200 mA supply. Available current = 139 mA
External Power SupplyIf a meter connected to the light/horn does not have an internal transmitter power supply or more power is required than the meter provides, then consider the PDA1024-01 24 VDC transmitter power supply.
