PROBLEM CAUSE ACTION TO TAKE:
4
⇒
GREEN LED IS ON, RED LED (PULSE) IS OFF, THE
PUMP DOES NOT PULSE
SOLENOID DATA TO CHECK WITH TESTER
CTRL2-7L types 1,5-10 / 2,5-15 / 5,5-07 / 07-04:
Ω 230
CTRL2-5L types 01-05 / 2,5-06 / 05-04 / 07-02
Ω 275
Disconnect the pump from power supply,
open dosing pump and disconnect solenoid
wires from pcb and, with a tester, measure
electrical resistance (check solenoid view
page
23) then contact manufacturer
Customer Service, Dealer or Distributor.
5
⇒
PUMP PULSES ARE NOT CONSTANT
Check that voltage is /- 10-15% of
rated voltage
6
⇒
DOSING PUMP GIVES ONLY ONE PULSE
Disconnect the equipment and contact
manufacturer Customer Service, Dealer or
Distributor.
7
⇒
DOSING PUMP
PULSES WORKING
NORMALLY, ALL
LEDS ON,
BUT FLOW
RATE IS MUCH LESS
THEN EXPECTED
cause 1: pumped additive
is very viscous or with high
specific weight a. Check liquid viscousity and if it’s higher then 500
cps change standard pump head with PMMA type
(viscous configuration)
b. If it’s not higher then 200 cps, using same pump
head, select higher performance dosing pump (at
least double flow rate of the one requested
cause 2: solenoid not
working properly Disconnect power supply, open dosing pump and
disconnect solenoid wires from pcb and, with a tester,
measure
electrical resistance then contact
manufacturer Customer Service, Dealer or Distributor.

⇒
LIQUID IS
LEAKING
- from back of the
pump head:
cause 1: diaphragm-pump
head o-ring is not sealing
because worned out or
faulty due to not
compatible with liquid. Check diaphragm-pump head o-ring and replace it
with new one or compatible one.
cause 2: pump head
screws are not well tighten. Tighten firmly pump head screws.
9
⇒
LEAKAGE
- from the pump head
nipples:
cause 1: nipple o-ring is
not sealing because worn
out or faulty because not
compatible with liquid. Check nipple o-ring and replace it with new one or
proper one compatible.
cause 2: hose is not
locked tight with tube nut. Tighten tube nut on hose.
10
⇒
HOSE BREAKING
Hoses are breaking
(mostly discharge one) and
liquid is coming out a. Ensure hose-nuts on the nipple (mostly discharge
side) are NOT over-tighten
b. ensure that hoses are straight, without angles
c. check chemical compatibility
11
⇒
FOR
CTRL2/L
ONLY
FLOATING LEVEL SWITCH NOT WORKING
a. Check that the connector male/female between
level probe and pump is securely fastened.
b. If problem persists make a short connection
between pin #3 and pin #4 with a wire or small pliers.
In case the level alarm LED turns ON, replace level
probe. If problem persists, contact distributor.
12
⇒
IN CASE ADDITIVE LEVEL IS BELOW THE
LEVEL PROBE AND LEVEL ALARM IS STILL OFF
Check the level switch connection as previous point b.,
in case the level switch is working and the level alarm
LED is still OFF, contact manufacturer customer
service, dealer or distributor
