LOCKOUT
Individual lockout is provided by means of a 10PST switch mounted at the bottom of each module.
(5PST on 5 counter versions). Access to this portion is accomplished by removing the locked
bezel. The switch can be actuated with the tip of a ball-point pen or any other pointed object. To
reinstate, push the top of the switch lever in firmly. The switch is numbered 1-10 from left to right
on 10 counter modules and 1-5 on 5 counter modules.
ANTI-SURGE DIODES
Diodes D5 and D6 are placed across the time delay relay (K2) and selected totalizer in the reverse
direction. Upon opening of the inductive circuit, the current surges through the diode, minimizing
pulser and K2 relay contact erosion.
HEATER
A heating element controlled by a thermostat set at 40
°
F protects electrical components when
temperatures fall below the recommended operating temperature. The heater/thermostat circuitry
is continuously connected to the 115 VAC (or 230 VAC) line, but will operate only when the
temperature drops below 40
°
F.
When an auxiliary unit is used, the 115 VAC or 230 VAC line must be connected from the master
unit for powering the heater, along with the other interconnections.
