Intermatic GRASSLIN DTAV40 Serie Instructions D'installation Et D'utilisation

DTAV40 Series
WARNING
Risk of Fire or Electric Shock
• Disconnect power at the circuit breaker(s) or disconnect switch(es) before beginning installation or servicing.
Do not use the off position of the timer for equipment servicing.
• More than one circuit breaker or disconnect switch may be required to de-energize the equipment before
servicing.
• Use COPPER conductors ONLY.
• For 40 amp loads, use #8 AWG wire, rated 90 degrees C min.
• Wire in accordance with national and local electrical code requirements.
• This Type 3R enclosure does not provide grounding between conduit connections. When metallic conduit is
used, you must also install grounding type bushings and jumper wire, in accordance withå the national
electrical code requirements.
• When replacing a timer with a metal bracket, replace the bracket with a non-metallic bracket. (Intermatic
Model DT-B is recommended.)
• For outdoor locations, raintight, or wet location, conduit hubs that comply with requirements of UL514B
(standard for fittings for conduit and outlet boxes) are to be used.
Risk of Damage to Timer
NOTICE
• Rotate timer dial clockwise only.
• Do not move the clock hands on the timer. Moving the clock hands can damage the timer.
Mode Selection Switch (S1)
UL TYPE 3R ENCLOSURE
Set Mode Selection (See S1 DIP Switch, table and instructions below).
MODE SELECTION (S1 DIP SWITCH):
First determine what model is being replaced (Grasslin or Competitors).
The mode selector DIP switch (located at lower right side of the board)
determines the configuration of terminals 2 & 4. In position "A", the
terminals are normally closed, and will open during a defrost. In position
"B", terminals 2 & 4 are normally open, and will close during a defrost.
Select proper position from table below and wiring diagrams indicated.
To select mode simply slide the switch as follows:
Mode A - position switch up;
Mode B - position switch down;
Note: When Mode "B" is selected the
DTAV40 will operate as follows:
Refrigeration Mode - Red & Green LEDs
will turn OFF (1 & 3 and 2 & 4 break while
1 & F make)
Defrost Mode - RED & GREEN LEDs will turn
ON (1 & 3 and 2 & 4 make while 1 & F break)
