Network Relays Types CAL16A and CAN13A
The reclose calibration of the relay can be
changed by adjusting the mechanical restraInt ele-
ment.
TurnIng the cap of the restraInt clockwIse
Increases the restraint and therefore the reclose
callbratton.
Holding Colis
Both holdIng-colis of the Type CAN13A relay
are rated 2 amperes.
These holdIng colis can b£'
checked as part of the trIp and reclose adjustments
above by connecttng an adjustable resIstor In the
contact cIrcuit and adJusttng the holdIng coli clrcult
to 2 amperes.
As soon as the trlp or reclose con-
tacts make, the sealing armature should deClnitely
seal them closed, and there should be no sparking
except at the Instant the contacts touch. Interrupt
the holdIng current by an external switch In the
contact cIrcuit, never at the conlaets.
TYPE
CAUSA
RELAY
The Type CAL16A relay Is Identtcal to the Type
CAL15A relay,
deserlbe~
In the Included Instruc-
tton book GEI-13580, except that
It
Is mounted In a
drawout case.
For callbratton, the relay should be
connected as shown In Fig. 5.
The normal call-
bratton of the Ty"e CAL16A relay Is to close Its
contacts when the phasIng voltage (on studs 7 -8) ts
gradual\¥ Increased to 0.5 volt, leading the potential
voltage (studs 5-6) by 90 degrees. Adjustments can
be made as described In GEI-J3580.
