M-2001 Checkout Procedure
NOTE:
This test of the M-2001 assumes that the
unit remains connected to the adapter panel.
Basic Operational Test
1.
Apply 120.0 V ac to TB1-9 (motor power)
and TB1-10 regulated voltage) of adapter
panel.
2.
Connect neutral to TB1-8 (neutral).
3.
Verify local voltage y input voltage
±0.3 V.
4.
Apply 100.0 mA in-phase current to
TB1-14 (load current-polarity) and
TB1-15 (load current-return) of the
adapter panel. Verify Control Load I y
100 mA and Power Factor y 1.0 ±0.02.

Checkout Procedure
NOTE:
All Beckwith Electric units are fully cali-
brated at the factory. There is no need to re-calibrate
the units before initial installation.
Set the
AUTO/OFF/MANUAL
switch to
OFF
.
Inspect the
MOTOR POWER
and
VOLTAGE
fuses
to ensure they are correctly sized and have not
blown.
6.1
Power
1.
Remove any external connection
between TB1-9 and TB1-10 which are
located on the adapter panel printed
circuit board. Also remove any voltage
applied to TB1-9 externally. Using a
voltmeter, make sure that the voltage
applied to TB1-10 is nominal 120 V ac
with respect to TB1-8 (neutral). Apply
power to TB1-10 (hot) and TB1-8
(neutral).

WARNING: Voltage applied at the METER OUT
test terminal may energize the regulator or trans-
former to a high voltage through the voltage
transformer.
Death or severe electrical shock can occur.
Do not connect any voltage source at the METER
OUT test terminal.
2.
Connect a voltmeter to the
METER OUT
test terminal on the front of the adapter
panel. 120 V ac should be indicated.

CAUTION:
Do not reverse the ground and hot
wires when connecting an external source. A 3 AG
fuse (F2) is installed to protect the relay from dam-
age if these connections are accidentally reversed.
Spare fuses are supplied inside the fuse holders.
Units returned with only a blown fuse are not cov-
ered by warranty, and a nominal repair charge will be
made for replacement of the fuse. Please check the
fuse before returning the unit for repair, in order to
avoid unnecessary repair charges.
