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-5C or any
controlled equipment.
Pour éviter la décharge électrique déconnectez toute la puissance avant d'ouvrir la couverture du DS-
5C.
Selecting a Mounting Location for the DS-5C
The interleaved grid on the top of the DS-5C is the precipitation or “moisture" sensor. The brass cylinder 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 sensor 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-5C must be mounted outdoors, away from furnace vents, dryer vents, and other sources of heat. Note that, when powered, the DS-5C moisture grid will always remain hot. This is normal. This allows the sensor to continuously melt snow and evaporate both rain and snow from the grid.
The DS-5C 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-5C for termination of the power and load pigtails to the building wiring.
Use Care When Replacing the Front Cover. Do Not Pinch the Gasket or Overtighten the Screws.

monitor relay. This relay, rated at 24 VAC/VDC @ 400 mA, 10W maximum, will close with the load relays and can be used to externally monitor activation of the sensor. This terminal block is also the connection point for connecting a CDP-2. Use only tinned, stranded, shielded cable for a reliable connection.
The DS-5C provides external control/monitor capability. Cable rated 300V up to 18 AWG can be connected to TB2 to access this feature. Connecting Black (4) to White (1) will activate the “Manual On” function. Connecting Green (5) to White (1) will activate the “Standby/Reset” function. See the “Manual Override Switch Function” for a description of these modes. The Red/Orange (2/3) leads are connected to an internal low power
Power & Activation Indicator
A green lamp shines through a lens on the cover of the DS-5C to indicate operational status. If this lamp is OFF the DS-5C is not receiving power. If this lamp is steady ON the DS-5C is powered but not triggered. If this lamp is FLASHING the DS-5C is powered on and triggered, the main relays are closed, and attached equipment should be activated. Note that, even though snow or rain may have stopped, the DS-5C indicator will continue to flash during the Delay-Off drying cycle.
Moisture Grid Maintenance & Replacement
It is recommended that the DS-5C be powered down and the grid wiped clean with clear water at least once every 4 months. Heavy deposits may be removed using a non-metallic scouring pad (Scotch-BriteTM or equivalent.) 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-5 “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-5C. Open the front cover and remove the cable connector from the Grid Jack. While holding the reducing bushing, unscrew and remove the old moisture grid. Pass the new moisture grid connector through the top hole and screw the assembly into the reducing bushing. Tighten the grid hand tight plus ¼ turn. Connect 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.
Use Care When Replacing the Front Cover. Do Not Pinch the Gasket or Overtighten the Screws.
Preseason Snow Detection Testing
It is always a good idea to test the operation of the DS-5C prior to the winter season. 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-5C, drip some of the water onto the moisture grid, 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-5C will activate. The user should hear the internal control relays close and see the green lamp blink. 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.
