The customer shall be responsible for all costs incurred in the removal or reinstallation and shipping of the
product for repairs. Within the limitations of this warranty, inoperative units should be returned, freight
prepaid, to ASE, and we will repair or replace, at our option, at no charge to you with return freight paid by
ASE. It is agreed that such repair or replacement is the exclusive remedy available from ASE and that

General Safety Instructions

1. THIS UNIT SHOULD BE INSTALLED, OPENED, AND REPAIRED BY QUALIFIED PERSONNEL

ONLY!

CETTE UNITÉ DEVRAIT ÊTRE INSTALLÉE, OUVERTE, ET RÉPARÉE PAR LE PERSONNEL

QUALIFIÉ SEULEMENT!

2. To avoid shock hazard do not open the front cover with power connected to the DS-2B or any controlled

equipment.

Pour éviter la décharge électrique déconnectez toute la puissance avant d'ouvrir la couverture du DS-

2B.

3. To avoid fire hazard replace fuse F1 with a 1/2 Amp 250 VAC 2AG fast acting fuse ONLY.
Pour éviter le risque d'incendie remplacez le fusible F1 par un fusible de 1/2 l'ampère 250 VCA 2AG

SEULEMENT.

Selecting a Mounting Location for the DS-2B

The interleaved grid on the top of the DS-2B is the precipitation sensor or “moisture grid.” The rubber “boot” protruding
from the bottom of the enclosure is the temperature sensor. For reliable rain and snow detection the unit must be
mounted in a location that exposes the moisture grid to a clear view of the sky. The unit should not be mounted directly
under eaves or overhangs. It should not be mounted so close to the ground that it may become buried in snow. For
proper temperature detection the DS-2B must be mounted outdoors, away from furnace vents, dryer vents, and other
sources of heat. Note that, when powered, the DS-2B moisture grid will always remain hot
the grid to continuously melt snow and evaporate both rain and snow from the grid.

The DS-2B can be mounted by screwing the base conduit hub onto an appropriate size free-standing conduit or by
using the mounting holes in each corner of the enclosure.

DO NOT DRILL HOLES THROUGH THE ENCLOSURE FOR MOUNTING!

NE FONT PAS LES TROUS DE FORET PAR LA BOÎTE POUR LE SUPPORT!

This can allow water into the enclosure causing a potential shock hazard. It is recommended that a weatherproof
junction box be mounted below the DS-2B for termination of the power and load pigtails to the building wiring.

Always Use Care When Replacing the Front Cover

Be sure the front cover gasket is not pinched or rolled. Do not overtighten the front cover screws.

An external control/monitor jack is provided on the DS-2B. Order

Connecting Black to White will activate the “Manual On” function.
Connecting Green to White will activate the “Standby/Reset”
function. The Red/Orange leads are connected to an internal low
power monitor relay. This relay, rated at 24 VAC/VDC at 400 ma,
will close with the load relay and can be used to externally monitor
activation of the sensor.

Moisture Grid Maintenance & Replacement

It is recommended that the DS-2B be powered down and the grid wiped clean with clear water at least
once every 4 months. Heavy deposits may be removed using Scotch-Brite. However, after a number of
years, the corrosive elements left behind when water is evaporated out of the moisture grid will eventually
damage the grid rings. The moisture grid can be easily replaced by ordering and installing an MG-1
“Moisture Grid Assembly” and following the procedure below:

THIS PROCEDURE SHOULD ONLY BE PERFORMED BY QUALIFIED PERSONNEL!

CE PROCÉDÉ DEVRAIT SEULEMENT ÊTRE EXÉCUTÉ PAR LE PERSONNEL QUALIFIÉ!

Open all power and load breakers connected to the DS-2B. Open the front cover and remove the cable
from the Grid Jack. While holding the reducing bushing, unscrew and remove the old moisture grid. Install
the supplied thread sealing tape, place the new grid into the top hole and screw the assembly into the
reducing bushing. Tighten the grid hand tight plus ¼ turn. Reconnect the new cable to the Grid Jack.
Confirm that the four connector pins are properly aligned with the jack. Close the front cover, confirming
that the front cover gasket is properly sealed. Reapply power.

Always Use Care When Replacing the Front Cover

Be sure the front cover gasket is not pinched or rolled. Do not overtighten the front cover screws.

Preseason Snow Detection Testing

It is always a good idea to test the operation of the DS-2B prior to the winter seas on. Procure some clean
water and, if the outdoor temperature is above the trigger point, a can of spray component cooler (Radio
Shack Part #64-4321 or equivalent.) Clean the moisture grid following the procedure outlined above and
allow it to dry. Apply power to the DS-2B and drip some of the water onto the moisture grid, and then spray
the temperature sensor protruding from the base of the enclosure with the component cooler. Once the
temperature sensor has reached the trigger point with water still present on the grid the DS-2B will activate.
The user should hear the internal control relay close. Proper operation has been confirmed. Allow the grid
to dry completely. To clear the Delay-Off timer place the override switch into “Standby/Reset”, and then
back to the “Automatic” position.
