Table 1 Timer Operation
Note: When the timer is energized or times out in the on-delay mode, an
N.O. contact may close before an N.C. contact opens; this can occur because
of inherent operating characteristics. Similarly, when the timer is de-energized
or times out in the off-delay mode, an N.C. contact may close before an N.O.
opens. Assured contact overlap or non-overlap cannot be provided in the same
device.
Terminals Terminal clamps are designed for solid or stranded copper wire (strip ends to
7.9mm [5/16”]). Use 7 - 8 lb.-in. of torque to tighten the terminal clamps. Wire
size: (1) #18 AWG (.75mm
2
) minimum to (2) #12 AWG (14.0mm
2
)
maximum.
Wiring Make connections as shown in Figure 3. Power is applied continuously to
terminals L1 and L2. Voltage applied and removed at initiating terminal P will
operate the instantaneous contacts and initiate timing as indicated in Table 1.
Use insulated copper wire rated at 75 ° C (167 ° F) or higher.
